The impact of the seasonal influenza and 2009 AH1N1 pandemic influenza on mortality is not yet completely understood, particularly in tropical and subtropical countries. The trends of influenza related mortality rate in different age groups and different outcomes on a area in tropical and subtropical climate with more than 41 million people (State of São Paulo, Brazil), were studied from 2002 to 2011 were studied. Serfling-type regression analysis was performed using weekly mortality registries and virological data obtained from sentinel surveillance. The prepandemic years presented a well-defined seasonality during winter and a clear relationship between activity of AH3N2 and increase of mortality in all ages, especially in individuals older than 60 years. The mortality due to pneumonia and influenza and respiratory causes associated with 2009 pandemic influenza in the age groups 0-4 years and older than 60 was lower than the previous years. Among people aged 5-19 and 20-59 years the mortality was 2.6 and 4.4 times higher than that in previous periods, respectively. The mortality in all ages was higher than the average of the previous years but was equal mortality in epidemics of AH3N2. The 2009 pandemic influenza mortality showed significant differences compared to other years, especially considering the age groups most affected.

Very elderly patients (age ≥ 85 years) are a rapidly increasing segment of the population. As a group, they experience high rates of in-hospital mortality and bleeding complications following percutaneous coronary intervention (PCI). However, the relationship between bleeding and mortality in the very elderly is unknown. Retrospective review was performed on 17,378 consecutive PCI procedures from 2000 to 2015 at Dartmouth-Hitchcock Medical Center. Incidence of bleeding during the index PCI admission (bleeding requiring transfusion, access site hematoma > 5 cm, pseudoaneurysm, and retroperitoneal bleed) and in-hospital mortality were reported for four age groups (< 65 years, 65-74 years, 75-84 years, and ≥ 85 years). The mortality of patients who suffered bleeding complications and those who did not was calculated and multivariate analysis was performed for in-hospital mortality. Lastly, known predictors of bleeding were compared between patients age < 85 years and age ≥ 85 years. Of 17,378 patients studied, 1019 (5.9%) experienced bleeding and 369 (2.1%) died in-hospital following PCI. Incidence of bleeding and in-hospital mortality increased monotonically with increasing age (mortality: 0.94%, 2.27%, 4.24% and 4.58%; bleeding: 3.96%, 6.62%, 10.68% and 13.99% for ages < 65, 65-74, 75-84 and ≥ 85 years, respectively). On multivariate analysis, bleeding was associated with increased mortality for all age groups except patients age ≥ 85 years [odds ratio (95% CI): age < 65 years, 3.65 (1.99-6.74); age 65-74 years, 2.83 (1.62-4.94); age 75-84 years, 3.86 (2.56-5.82), age ≥ 85 years: 1.39 (0.49-3.95)]. Bleeding and mortality following PCI increase with increasing age. For the very elderly, despite high rates of bleeding, bleeding is no longer predictive of in-hospital mortality following PCI.

Purpose This study aims to examine how inequalities in suicide by education changed during and after macroeconomic restructuring following the economic crisis of 1997 in South Korea. Materials and Methods Using Korea's 1995, 2000, and 2005 census data aggregately linked to mortality data (1993 - 2006), relative and absolute differentials in suicide mortality by education were calculated by gender and age among Korean population aged 35 and over. Results Average annual suicide mortality rates have steadily increased from 1993 - 1997 to 2003 - 2006 in almost all sociodemographic groups stratified by gender, age, and education. Based on the relative index of inequality (RII) and slope index of inequality (SII), educational differentials in suicide mortality generally increased over time in men and women aged 45 years +. Although RII did not increase with year among men and women aged 35 - 44 years, SII showed a significantly increasing trend in this age group. Conclusion These worsening absolute inequalities in suicide mortality indicate that the governmental suicide prevention policy should be directed toward socially disadvantaged groups of the Korean population.

Determine the relationship between liver function test results (GGT, alkaline phosphatase, AST, and ALT) and all-cause mortality in life insurance applicants. By use of the Social Security Master Death File, mortality was examined in 1,905,664 insurance applicants for whom blood samples were submitted to the Clinical Reference Laboratory. There were 50,174 deaths observed in this study population. Results were stratified by 3 age/sex groups: females, age <60; males, age <60; and all, age 60+. Liver function test values were grouped using percentiles of their distribution in these 3 age/sex groups, as well as ranges of actual values. Using the risk of the middle 50% of the population by distribution as a reference, relative mortality observed for GGT and alkaline phosphatase was linear with a steep slope from very low to relatively high values. Relative mortality was increased at lower values for both AST and ALT. ALT did not predict mortality for values above the middle 50% of its distribution. GGT and alkaline phosphatase are significant predictors of mortality risk for all values. ALT is still useful for triggering further testing for hepatitis, but AST should be used instead to assess mortality risk linked with transaminases.

To determine the characteristics and trends of diabetes mortality among the Puerto Rican population from 1980 through 1997. Death certificates for Puerto Rican residents whose underlying cause of death was diabetes mellitus (ICD-9-250.0) were reviewed, and sociodemographic information was abstracted. The proportion mortality ratio (PMR) and 95% confidence intervals were calculated by gender, age group, educational level and period of time. Trend analysis in mortality was performed using a Poisson regression model. A total of 26,193 deaths (5.8%) were primarily attributed to diabetes mellitus in the study period. Females accounted for 55.8% of all diabetes related deaths. Diabetes accounted for a higher proportion of deaths among persons aged 60-64 years (8.14%), persons aged 65-74 (8.12%), females (7.73%) and those with 1-6 years of education (7.08%). The PMR steadily increased from 4.55% in the 1980-85 period to 6.91% in the 1992-97 period. There was a higher mortality in male diabetic subjects aged < or = 64 than in females during the 18 year period. Between 1980 and 1991, females aged 65-74 had a higher mortality than males, however, mortality increased in males of the same age group during 1992-97. When the oldest age group (> or = 75) was examined, males had a higher mortality between 1986 and 1997, whereas females had a slightly higher rate between 1980 and 1985. Our results indicate that diabetes mortality has been markedly increasing in the Puerto Rican population, primarily in persons aged 65 years or more. Further analysis is needed to evaluate the determinants of mortality in diabetes.

To analyze the demographic characteristics and the death causes of the residents in Anhui province, and provide evidence for the disease prevention and control. Using descriptive epidemiological analysis, the demographic characteristics and death data of the national disease surveillance points (DSPs) in Anhui province in 2013 were analyed by areas. The aging of the population was observed in all the areas in Anhui, which was most obvious in Jianghuai, followed by Wannan and Huaibei. The overall mortality was 627.10/100 000. The mortalities of diseases varied with sex, area and age. Among the 3 areas, the overall mortality, chronic disease mortality and injury mortality were highest in Huaibei and lowest in Wannan. The area specific difference in mortality of infectious diseases was small. Regardless of areas or the types of diseases, the mortality was higher in males than in females. Deaths caused by diseases with unknown origins were common in residents aged >65 years. The mortality of chronic diseases was higher in residents aged >45 years, especially in those aged 65-84 years. The mortality of injuries was higher in age groups >15 years and >45 years. The mortality of infectious diseases peaked at both young age group and old age group. The top five death causes were cerebrovascular diseases, malignant tumors, heart diseases, respiratory diseases and injuries. Regardless of sex or area, the major death causes were similar, but the ranks were slightly different. The major death causes varied in different age groups, but they were similar in same age group in different areas. The major death causes were diseases originated in perinatal period, and congenital malformations, deformations and chromosomal abnormalities in children aged <1 year. The major death causes in children aged 1-14 years were injuries, diseases originated in perinatal period, congenital malformations, deformations and chromosomal abnormalities. Injuries and malignant tumors were the first and second death causes in residents aged 15-44 years. Malignant tumors, injuries, cerebrovascular diseases and heart diseases were the major death causes in residents aged 45-64 years. The major death causes were cerebrovascular diseases, malignant tumors, heart diseases and respiratory diseases in residents aged 65-84 years and heart diseases, cerebrovascular diseases, respiratory diseases and malign tumors in residents aged≥85 years. The major death causes in residents in Anhui province were cerebrovascular diseases, malignant tumors and injuries. Close attention should be paid to the prevention and control of cerebrovascular diseases, malignant tumors and heart diseases in age group≥45 years. It is necessary to strengthen the prevention and control of injuries in age group 15-44 years. Huaibei is a key area of disease prevention and control in Anhui, especially chronic disease and injury preventions.

Ethical and health care economic concerns surround the use of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in elderly patients. Patients requiring VA-ECMO are often in critical condition and the decision to cannulate is time-sensitive. We investigated the relationship between age and VA-ECMO outcomes to better inform this decision. This is a retrospective study of 355 patients placed on VA-ECMO between March 2007 and August 2016 at our institution. Using piecewise modelling, age became associated with in-hospital mortality after 63 years. Based on further analysis with the χ2 statistic maximization, patients were divided into 2 age groups: ≤72 years old [Group Y (Young), n = 310] and >72 years old [Group O (Old), n = 45]. Multivariable logistic regression was performed to identify preoperative predictors of in-hospital mortality. Patients over the age of 72 had a significantly higher prevalence of comorbidities, including coronary disease, previous strokes and chronic kidney disease. Weaning from ECMO was achieved in 76% of Group Y and 47% of Group O (P < 0.001). In-hospital mortality was 52% among Group Y and 69% among Group O (P = 0.037). Multivariable logistic regression using preoperative risk factors identified coronary artery disease, acute decompensated heart failure and an age >72 years as independent predictors of mortality (age >72 years: odds ratio 2.71, 95% confidence interval 1.22-6.00; P = 0.01). VA-ECMO in-hospital mortality is considerable across all age groups. However, age only becomes associated with mortality after 63 years and rises dramatically after 72 years. This study provides useful insight into these time-sensitive decisions for the development of possible practice guidelines. © The Author(s) 2018.

Racial residential segregation has been associated with an increased risk for heart disease and stroke deaths. However, there has been little research into the role that candidate mediating pathways may play in the relationship between segregation and heart disease or stroke deaths. In this study, we examined the relationship between metropolitan statistical area (MSA)-level segregation and heart disease and stroke mortality rates, by age and race, and also estimated the effects of various educational, economic, social, and health-care indicators (which we refer to as pathways) on this relationship. We used Poisson mixed models to assess the relationship between the isolation index in 265 U.S. MSAs and county-level (heart disease, stroke) mortality rates. All models were stratified by race (non-Hispanic black, non-Hispanic white), age group (35-64 years, ≥ 65 years), and cause of death (heart disease, stroke). We included each potential pathway in the model separately to evaluate its effect on the segregation-mortality association. Among blacks, segregation was positively associated with heart disease mortality rates in both age groups but only with stroke mortality rates in the older age group. Among whites, segregation was marginally associated with heart disease mortality rates in the younger age group and was positively associated with heart disease mortality rates in the older age group. Three of the potential pathways we explored attenuated relationships between segregation and mortality rates among both blacks and whites: percentage of female-headed households, percentage of residents living in poverty, and median household income. Because the percentage of female-headed households can be seen as a proxy for the extent of social disorganization, our finding that it has the greatest attenuating effect on the relationship between racial segregation and heart disease and stroke mortality rates suggests that social disorganization may play a strong role in the elevated rates of heart disease and stroke found in racially segregated metropolitan areas.

Background Globally, opioid drug use is an important cause of premature mortality. In many countries, opioid using populations are ageing. The current study investigates mortality in a large cohort of opioid users; with a focus on testing whether excess mortality changes with age. Methods 198,247 opioid users in England were identified from drug treatment and criminal justice sources (April, 2005 to March, 2009) and linked to mortality records. Mortality rates and standardised mortality ratios (SMRs) were calculated by age-group and gender. Results There were 3974 deaths from all causes (SMR 5.7, 95% Confidence Interval: 5.5 to 5.9). Drug-related poisonings (1715) accounted for 43% of deaths. Relative to gender-and-age-appropriate expectation, mortality was elevated for a range of major causes including: infectious, respiratory, circulatory, liver disease, suicide, and homicide. Drug-related poisoning mortality risk continued to increase beyond 45 years and there were age-related increases in SMRs for specific causes of death (infectious, cancer, liver cirrhosis, and homicide). A gender by age-group interaction revealed that whilst men have a greater drug-related poisoning mortality risk than women at younger ages, the difference narrows with increasing age. Conclusion Opioid users’ excess mortality persists into old age and for some causes is exacerbated. This study highlights the importance of managing the complex health needs of older opioid users.

2015-01-01

The Obesity Surgery Mortality Risk Score (OS-MRS) was developed to ascertain preoperative mortality risk of patients having bariatric surgery. To date there has not been a comparison between open and laparoscopic operations using the OS-MRS. To determine whether there are differences in mortality risk between open and laparoscopic Roux-en-Y Gastric Bypass (RYGB) using the OS-MRS. Three university-affiliated hospitals. The 90-day mortality of 2467 consecutive patients who had primary open (1574) or laparoscopic (893) RYGB performed by one surgeon was determined. Univariate and multivariate analysis using 5 OS-MRS risk factors including body mass index (BMI) gender, age>45, presence of hypertension and preoperative deep vein thrombosis (DVT) risk was performed in each group. Each patient was placed in 1 of 3 OS-MRS risk classes based on the number of risks: A (0-1), B (2-3), and C (4-5). Preoperative BMI and DVT risk factors were significantly greater in the open group (OG). Preoperative age was significantly greater in the laparoscopic group (LG). There were significantly more class B and C patients in LG. Ninety-day mortality rates for OG and LG patients were 1.0% and .9%, respectively. Pulmonary embolism was the most common cause of death. All deaths in LG occurred during first 4 years of that experience. Mortality rate by class was A = .1%; B = 1.5%; C = 2.3%. The difference in mortality between class B and C patients was not significant. Univariate analysis in the OG indicated that BMI, age, gender, and DVT risk were significant predictors of mortality. In the LG only BMI and DVT were significant predictors of death. Presence of hypertension was not a significant predictor in either group. Multivariate analysis excluding hypertension found that age was predictive of mortality in the OG while BMI (P = .057) and gender (P = .065) approached statistical significance. Conversely, only BMI was predictive of mortality in the LG with age approaching significance (P = .058). In multivariate analysis DVT risk was not predictive of mortality in either group. There are significant differences in the predictive value of the OS-MRS between open and laparoscopic RYGB. Although laparoscopic patients were significantly older versus the open patients, age was not predictive of mortality after laparoscopic RYGB. BMI trended toward increased mortality risk in both groups. Changes in technique and protocol likely contributed toward no mortality during the last 6 years of our laparoscopic experience.

On the derivation of a full life table from mortality data recorded in five-year age groups.

PubMed

Pollard, J H

1989-01-01

Mortality data are often gathered using 5-year age groups rather than individual years of life. Furthermore, it is common practice to use a large open-ended interval (such as 85 and over) for mortality data at the older ages. These limitations of the data pose problems for the actuary or demographer who wishes to compile a full and accurate life table using individual years of life. The author devises formulae which handle these problems. He also devises methods for handling mortality during the 1st year of life and for dealing with other technical problems which arise in the compilation of the full life table from grouped data.

Decreases in Smoking-Related Cancer Mortality Rates Are Associated with Birth Cohort Effects in Korean Men.

Background: This study aimed to examine trends in smoking-related cancer mortality rates and to investigate the effect birth cohort on smoking-related cancer mortality in Korean men. Methods: The number of smoking-related cancer deaths and corresponding population numbers were obtained from Statistics Korea for the period 1984-2013. Joinpoint regression analysis was used to detect changes in trends in age-standardized mortality rates. Birth-cohort specific mortality rates were illustrated by 5 year age groups. Results: The age-standardized mortality rates for oropharyngeal decreased from 2003 to 2013 (annual percent change (APC): -3.1 (95% CI, -4.6 to -1.6)) and lung cancers decreased from 2002 to 2013 (APC -2.4 (95% CI -2.7 to -2.2)). The mortality rates for esophageal declined from 1994 to 2002 (APC -2.5 (95% CI -4.1 to -0.8)) and from 2002 to 2013 (APC -5.2 (95% CI -5.7 to -4.7)) and laryngeal cancer declined from 1995 to 2013 (average annual percent change (AAPC): -3.3 (95% CI -4.7 to -1.8)). By the age group, the trends for the smoking-related cancer mortality except for oropharyngeal cancer have changed earlier to decrease in the younger age group. The birth-cohort specific mortality rates and age-period-cohort analysis consistently showed that all birth cohorts born after 1930 showed reduced mortality of smoking-related cancers. Conclusions: In Korean men, smoking-related cancer mortality rates have decreased. Our findings also indicate that current decreases in smoking-related cancer mortality rates have mainly been due to a decrease in the birth cohort effect, which suggest that decrease in smoking rates.

Stroke is an international health problem with high associated human and economic costs. The mortality rate from stroke in Russia is one of the highest in the world. Risk factors identification is therefore a high priority from the public health perspective. Epidemiological evidence suggests that binge drinking is an important determinant of high stroke mortality rate in Russia. The aim of the present study was to estimate the premature stroke mortality attributable to alcohol abuse in Russia on the basis of aggregate-level data of stroke mortality and alcohol consumption. Age-standardized sex-specific male and female stroke mortality data for the period 1980-2005 and data on overall alcohol consumption were analyzed by means ARIMA time series analysis. The results of the analysis suggest that 26.8% of all male stroke deaths and 18.4% female stroke deaths in Russia could be attributed to alcohol. The estimated alcohol-attributable fraction for men ranged from 16.2% (75+ age group) to 57,5% (30-44 age group) and for women from 21.7% (60-74 age group) and 43.5% (30- 44 age group). The outcomes of this study provide support for the hypothesis that alcohol is an important contributor to the high stroke mortality rate in Russian Federation. Therefore prevention of alcohol-attributable harm should be a major public health priority in Russia. Given the distribution of alcohol-related stroke deaths, interventions should be focused on the young and middle-aged men and women.

Temporal trends and ethnic variations in asthma mortality in Singapore, 1976-1995.

A study was undertaken to examine temporal trends and ethnic differences in the asthma mortality rate in Singapore. Asthma mortality rates in Singapore were estimated from vital data for the years from 1976 to 1995. Trends in sex and age specific (5-14, 15-34, 35-59, 60+ years) rates were obtained for four periods (1976-80, 1981-85, 1986-90, 1991-95) and for Chinese, Malay, and Indian subjects for the years when these data were available (1989-95). An increase in asthma mortality was observed in children aged 5-14 years from 0.21 per 100,000 person years in 1976-80 to 0.72 per 100,000 person years in 1991-95. No increases were noted in the other age groups but a small decrease was observed in the 1991-95 period for the 35-59 year age group. Marked ethnic differences in mortality rates were observed. In the group aged 5-34 years the asthma mortality rates were 0.5 per 100,000 in Chinese subjects, 1.3 per 100,000 in Indians, and 2.5 per 100,000 in Malay subjects. Similar 2-4 fold differences were observed in all other age groups. Apart from genetic factors, environmental exposures and medical care factors which influence asthma prevalence and severity are most likely to be the causes of the observed temporal trends and ethnic differences in the asthma mortality rate in Singapore, but further studies are needed to elucidate these more fully.

The great decline in infant mortality in Chile in the last 2 decades provokes interest in the current situation in child mortality (for children 1-4 years of age). For the present analysis, central death rates and probabilities of dying are used, calculated with Greville's method from birth and death data. Mortality trends of the group between 1961-78, sex differentials, and causes of death are studied. The findings indicate that mortality in this age group has declined dramatically during the period of analysis, mainly due to the decrease in mortality from respiratory diseases, diarrhea, and diseases avoidable through vaccination. To attain the future approach of the Chilean rate to that of more developed countries, the reduction of mortality from respiratory diseases and diarrhea should continue together with the achievement of substantial reduction in mortality from violence and accidents. This, the primary cause of death in children, ages 1-4, has not varied during the period under study. (author's)

European comparative studies documented a clear North-South divide in socioeconomic inequalities with cancer being the most important contributor to inequalities in total mortality among middle aged men in Latin Europe (France, Spain, Portugal, Italy). The aim of this paper is to investigate educational inequalities in mortality by gender, age and causes of death in France, with a special emphasis on people aged 75 years and more. We used data from a longitudinal population sample that includes 1% of the French population. Risk of death (total and cause specific) in the period 1990-1999 according to education was analysed using Cox regression models by age group (45-59, 60-74, and 75+). Inequalities were quantified using both relative (ratio) and absolute (difference) measures. Relative inequalities decreased with age but were still observed in the oldest age group. Absolute inequalities increased with age. This increase was particularly pronounced for cardiovascular diseases. The contribution of different causes of death to absolute inequalities in total mortality differed between age groups. In particular, the contribution of cancer deaths decreased substantially between the age groups 60-74 years and 75 years and more, both in men and in women. This study suggests that the large contribution of cancer deaths to the excess mortality among low educated people that was observed among middle aged men in Latin Europe is not observed among French people aged 75 years and more. This should be confirmed among other Latin Europe countries.

This study aims to determine the cardiac dysfunction prevalence, to investigate the relationship between the Short Physical Performance Battery (SPPB) test and structural and functional echocardiographic parameters and to determine whether SPPB scores and cardiac dysfunction are independent mortality predictors in an elderly Russian population. A random sample of 284 community-dwelling adults aged 65 and older were selected from a population-based register and divided into two age groups (65-74 and ≥75). The SPPB test, echocardiography and all-cause mortality were measured. The prevalence of cardiac dysfunction was 12% in the 65-74 group and 23% in the ≥75 group. The multivariate models could explain 15% and 23% of the SPPB score total variance for the 65-74 and ≥75 age groups, respectively. In the younger age group, the mean follow-up time was 2.6±0.46 years, and the adjusted hazard ratio (HR) for risk of mortality from cardiac dysfunction was 4.9. In the older age group, the mean follow-up time was 2.4±0.61 years, and both cardiac dysfunction and poor physical performance were found to be independent predictors of mortality (adjusted HR=3.4 and adjusted HR=4.2, respectively). The cardiac dysfunction prevalence in this elderly Russian population was found to be comparable to, or even lower than, reported prevalences for Western countries. Furthermore, the observed correlations between echocardiographic abnormalities and SPPB scores were limited. Cardiac dysfunction was shown to be a strong mortality predictor in both age groups, and poor physical performance was identified as an independent mortality predictor in the oldest subjects.

Mental illness, substance abuse, and poverty are risk factors for violent injury, and violent injury is a risk factor for early mortality that can be attenuated through hospital-based violence intervention programs. Most of these programs focus on victims under the age of 30 years. Little is known about risk factors or long-term mortality among older victims of violent injury. To explore the prevalence of risk factors for violent injury among younger (age < 30 years) and older (age 30 ≥ years) victims of violent injury, to determine the long-term mortality rates in these age groups, and to explore the association between risk factors for violent injury and long-term mortality. Adults with violent injuries were enrolled between 2001 and 2004. Demographic and injury data were recorded on enrollment. Ten-year mortality rates were measured. Descriptive analysis and logistic regression were used to compare older and younger subjects. Among 541 subjects, 70% were over age 30. The overall 10-year mortality rate was 15%, and was much higher than in the age-matched general population in both age groups. Risk factors for violent injury including mental illness, substance abuse, and poverty were prevalent, especially among older subjects, and were each independently associated with increased risk of long-term mortality. Mental illness, substance abuse, and poverty constitute a "lethal triad" that is associated with an increased risk of long-term mortality among victims of violent injury, including both younger adults and those over age 30 years. Both groups may benefit from targeted risk-reduction efforts. Emergency department visits offer an invaluable opportunity to engage these vulnerable patients. Copyright © 2018 Elsevier Inc.

The Millennium Development Goal 4 (MDG4) to reduce mortality in children aged <5 years by two-thirds from 1990 to 2015 has made substantial progress. We describe the contribution of measles mortality reduction efforts, including those spearheaded by the Measles Initiative (launched in 2001, the Measles Initiative is an international partnership committed to reducing measles deaths worldwide and is led by the American Red Cross, the Centers for Disease Control and Prevention, UNICEF, the United Nations Foundation, and the World Health Organization). We used published data to assess the effect of measles mortality reduction on overall and disease-specific global mortality rates among children aged <5 years by reviewing the results from studies with the best estimates on causes of deaths in children aged 0-59 months. The estimated measles-related mortality among children aged <5 years worldwide decreased from 872,000 deaths in 1990 to 556,000 in 2001 (36% reduction) and to 118,000 in 2008 (86% reduction). All-cause mortality in this age group decreased from >12 million in 1990 to 10.6 million in 2001 (13% reduction) and to 8.8 million in 2008 (28% reduction). Measles accounted for about 7% of deaths in this age group in 1990 and 1% in 2008, equal to 23% of the global reduction in all-cause mortality in this age group from 1990 to 2008. Aggressive efforts to prevent measles have led to this remarkable reduction in measles deaths. The current funding gap and insufficient political commitment for measles control jeopardizes these achievements and presents a substantial risk to achieving MDG4. © The Author 2011.

In France, the August 2003 heat wave was responsible for considerable excess mortality among the elderly. We wonder whether the dependency level could be a marker of the risk for mortality during this heat wave. Retrospective cohort study of deaths that occurred between 1 and 20 August 2003, conducted in five departments in the Paris area (Ile-de-France) among the beneficiaries of the Allocation personnalisée d'autonomie (APA), a stipend specifically allocated to dependent subjects > or =60 years of age. Their dependency level was determined by the GIR group (defined by the French law) used to fix the APA amount. Subjects' GIR group classification and demographic variables were obtained from departmental administrative files. Among the 31,603 APA beneficiaries alive on 31 July 2003, 16,779 were community dwellers and 14,824 lived in institutions. Between 1 and 20 August 2003, 858 subjects died: 300 community dwellers and 558 institutionalised (mortality rates of 2.7, 1.8 and 3.8 per cent, respectively). Independent risk factors for mortality were: age, sex and GIR group in community dwellers; age, GIR group and living in a region highly exposed to heatwave mortality for institutionalised elderly; independent factors for mortality were age, sex, GIR group, type of residence (institution/community), living in a region highly exposed to heatwave mortality and income for the overall population. The dependency level was associated with mortality during the 2003 heatwave in France, especially for elderly community dwellers. Dependency might help identify high-risk subjects and guide targeted prevention measures against heatwave-associated mortality.

The objective of this study was to analyze the burden of disease due to suicide in Mexico using years of life lost (YLL) between 2000 and 2012 by sex, age group (for those under 85 years of age) and jurisdiction. Vital statistics on mortality and population estimates were used to calculate standardized mortality rates and years of life lost due to suicide. Between 2000 and 2012 a sustained increase in the suicide mortality rate was observed in Mexico. The age group with the highest rate was 85 years of age or older for men, and 15-19 years of age for women. The highest impact in life expectancy due to suicide occurred at 20 to 24 years of age in men and 15 to 19 years of age in women. The states with the highest mortality due to suicide were located in the Yucatan Peninsula (Yucatan, Quintana Roo and Campeche). Mortality due to suicide in Mexico has increased continually. As suicides are preventable, the implementation of health public policies through timely identification, integral prevention strategies and the detailed study of associated risk factors is imperative.

To determine if coronary artery calcium (CAC) scoring is independently predictive of mortality in young adults and in the elderly population and if a young person with high CAC has a higher mortality risk than an older person with less CAC. We studied a cohort of 44 052 asymptomatic patients referred for CAC scans for cardiovascular risk stratification. All-cause mortality rates (MRs) were calculated after stratifying by age groups (<45, 45-54, 55-64, 65-74, and ≥75) and CAC score (0, 1-100, 100-400, and >400). Multivariable Cox regression models were constructed to assess the independent value of CAC for predicting all-cause mortality in the <45- and ≥75-year-old age groups. The MR increased in both the <45- and ≥75-year-old age groups with an increasing CAC group. After multivariable adjustment, increasing CAC remained independently predictive of increased mortality compared with CAC = 0 [<45 age group, hazard ratio (95% confidence interval): CAC = 1-100, 2.3 (1.2-4.2); CAC = 100-400, 7.4 (3.3-16.6); CAC > 400, 34.6 (15.5-77.4); ≥75 age group: CAC = 1-100, 7.0 (2.4-20.8); CAC = 100-400, 9.2 (3.2-26.5); CAC > 400, 16.1 (5.8-45.1)]. Persons <45 years old with CAC = 100-400 and CAC > 400 had 2- and 10-fold increased MRs, respectively, compared with persons ≥75 with no CAC. Individuals ≥75 years old with CAC = 0 had a 5.6-year survival rate of 98%, similar to those in other age groups with CAC = 0 (5.6-year survival, 99%). The value of CAC for predicting mortality extends to both elderly patients and those <45 years old. Elderly persons with no CAC have a lower MR than younger persons with high CAC.

We compared clinical characteristics and cancer specific mortality in men diagnosed with prostate cancer before vs after age 50 years. A total of 919 men 35 to 49 years old and 45,098 men 50 to 66 years old who were diagnosed with prostate cancer between 1998 and 2012 were identified in PCBaSe (Prostate Cancer data Base Sweden). Cancer specific mortality was compared among age groups (35 to 49, 50 to 59, 60 to 63 and 64 to 66 years) with and without adjusting for cancer characteristics, comorbidity and education in a multivariable Cox proportional hazards model. Clinical cancer characteristics indicated that most nonmetastatic cancer in men younger than 50 years was detected after prostate specific antigen testing. The proportion of nonmetastatic vs metastatic disease at diagnosis was similar in all age groups. A strong association between younger age and poor prognosis was apparent in men in whom metastatic disease was diagnosed before age 50 to 55 years. The crude and adjusted HRs of cancer specific mortality were 1.41 (95% CI 1.12-1.79) and 1.28 (95% CI 1.01-1.62) in men diagnosed before age 50 and at age 50 to 59 years, respectively. In men with nonmetastatic disease crude cancer specific mortality increased with older age but adjusted cancer specific mortality was similar in all age groups. Our findings suggest that an aggressive form of metastatic prostate cancer is particularly common in men younger than 50 to 55 years. Genetic studies and trials of intensified systemic treatment are warranted in this patient group. Copyright © 2017 American Urological Association Education and Research, Inc.

Marked variations exist in the incidence and mortality trends of major cancers in South-Eastern European (SEE) countries which have now been detailed by age for breast cancer (BC) to seek clues for improvement. We brought together and analysed data from 14 cancer registries (CRs), situated in SEE countries or directly adjacent. Age-standardised rate at world standard (ASRw) and truncated incidence and mortality rates during 2000-2010 by year, and for four age groups, were calculated. Average annual percentage change of rates was estimated using Joinpoint regression. Annual incidence rates increased significantly in countries and age groups, by 2-4% (15-39 years), 2-5% (40-49), 1-4% (50-69) and 1-6% (at 70+). Mortality rates decreased significantly in all age-groups in most countries, but increased up to 5% annually above age 55 in Ukraine, Serbia, Moldova and Cyprus. The BC data quality was evaluated by internationally agreed indicators which appeared suboptimal for Moldova, Bosnia and Herzegovina and Romania. The observed variations of incidence trends reflect the influence of risk factors, as well as levels of early detection activities (screening). While mortality rates were mostly decreasing, probably due to improved cancer care and introduction of more effective systemic treatment regimens, the worrying increasing mortality trends in the 55-plus age groups in some countries have to be addressed by health professionals and policymakers. In order to assess and monitor the effects of cancer control activities in the region, the CRs need substantial investments. Copyright © 2017 Elsevier Ltd. All rights reserved.

Population density, socioeconomic environment and all-cause mortality: a multilevel survival analysis of 2.7 million individuals in Denmark.

This study examines the relative effects of population density and area-level SES on all-cause mortality in Denmark. A shared frailty model was fitted with 2.7 million persons aged 30-81 years in 2,121 parishes. Residence in areas with high population density increased all-cause mortality for all age groups. For older age groups, residence in areas with higher proportions of unemployed persons had an additional effect. Area-level factors explained considerably more variation in mortality among the elderly than among younger generations. Overall this study suggests that structural prevention efforts in neighborhoods could help reduce mortality when mediating processes between area-level socioeconomic status, population density and mortality are found.

OBJECTIVE: To analyse trends in mortality inequalities in Barcelona between 1983 and 1994 by comparing rates in those electoral wards with a low socioeconomic level and rates in the remaining wards. DESIGN: Mortality trends study. SETTING: The city of Barcelona (Spain). SUBJECTS: The study included all deaths among residents of the two groups of city wards. Details were obtained from death certificates. MAIN OUTCOME MEASURES: Age standardised mortality rates, age standardised rates of years of potential life lost, and age specific mortality rates in relation to cause of death, sex, and year were computed as well as the comparative mortality figure and the ratio of standardised rates of years of potential life lost. RESULTS: Rates of premature mortality increased from 5691.2 years of potential life lost per 100,000 inhabitants aged 1 to 70 years in 1983 to 7606.2 in 1994 in the low socioeconomic level wards, and from 3731.2 to 4236.9 in the other wards, showing an increase in inequalities over the 12 years, mostly due to AIDS and drug overdose as causes of death. Conversely, cerebrovascular disease showed a reduction in inequality over the same period. Overall mortality in the 15-44 age group widened the gap between both groups of wards. CONCLUSION: AIDS and drug overdose are emerging as the causes of death that are contributing to a substantial increase in social inequality in terms of premature mortality, an unreported observation in European urban areas.

Mortality Trajectories at Exceptionally High Ages: A Study of Supercentenarians

The growing number of persons surviving to age 100 years and beyond raises questions about the shape of mortality trajectories at exceptionally high ages, and this problem may become significant for actuaries in the near future. However, such studies are scarce because of the difficulties in obtaining reliable age estimates at exceptionally high ages. The current view about mortality beyond age 110 years suggests that death rates do not grow with age and are virtually flat. The same assumption is made in the new actuarial VBT tables. In this paper, we test the hypothesis that the mortality of supercentenarians (persons living 110+ years) is constant and does not grow with age, and we analyze mortality trajectories at these exceptionally high ages. Death records of supercentenarians were taken from the International Database on Longevity (IDL). All ages of supercentenarians in the database were subjected to careful validation. We used IDL records for persons belonging to extinct birth cohorts (born before 1895) since the last deaths in IDL were observed in 2007. We also compared our results based on IDL data with a more contemporary database maintained by the Gerontology Research Group (GRG). First we attempted to replicate findings by Gampe (2010), who analyzed IDL data and came to the conclusion that “human mortality after age 110 is flat.” We split IDL data into two groups: cohorts born before 1885 and cohorts born in 1885 and later. Hazard rate estimates were conducted using the standard procedure available in Stata software. We found that mortality in both groups grows with age, although in older cohorts, growth was slower compared with more recent cohorts and not statistically significant. Mortality analysis of more numerous 1884–1894 birth cohort with the Akaike goodness-of-fit criterion showed better fit for the Gompertz model than for the exponential model (flat mortality). Mortality analyses with GRG data produced similar results. The remaining life expectancy for the 1884–1894 birth cohort demonstrates rapid decline with age. This decline is similar to the computer-simulated trajectory expected for the Gompertz model, rather than the extremely slow decline in the case of the exponential model. These results demonstrate that hazard rates after age 110 years do not stay constant and suggest that mortality deceleration at older ages is not a universal phenomenon. These findings may represent a challenge to the existing theories of aging and longevity, which predict constant mortality in the late stages of life. One possibility for reconciliation of the observed phenomenon and the existing theoretical consideration is a possibility of mortality deceleration and mortality plateau at very high yet unobservable ages.

ABSTRACT Objective: To analyze mortality from idiopathic pulmonary fibrosis (IPF) in Brazil over the period 1979-2014. Methods: Microdata were extracted from the Brazilian National Ministry of Health Mortality Database. Only deaths for which the underlying cause was coded as International Classification of Diseases version 9 (ICD-9) 515 or 516.3 (until 1995) or as ICD version 10 (ICD-10) J84.1 (from 1996 onward) were included in our analysis. Standardized mortality rates were calculated for the 2010 Brazilian population. The annual trend in mortality rates was analyzed by joinpoint regression. We calculated risk ratios (RRs) by age group, time period of death, and gender, using a person-years denominator. Results: A total of 32,092 deaths were recorded in the study period. Standardized mortality rates trended upward, rising from 0.24/100,000 population in 1979 to 1.10/100,000 population in 2014. The annual upward trend in mortality rates had two inflection points, in 1992 and 2008, separating three distinct time segments with an annual growth of 2.2%, 6.8%, and 2.4%, respectively. The comparison of RRs for the age groups, using the 50- to 54-year age group as a reference, and for the study period, using 1979-1984 as a reference, were 16.14 (14.44-16.36) and 6.71 (6.34-7.12), respectively. Men compared with women had higher standardized mortality rates (per 100,000 person-years) in all age groups. Conclusion: Brazilian IPF mortality rates are lower than those of other countries, suggesting underdiagnosis or underreporting. The temporal trend is similar to those reported in the literature and is not explained solely by population aging. PMID:29340493

A steadily increasing pattern of breast cancer mortality has been reported in South Korea since the late 1980s. This paper explored the trends of educational inequalities of female breast cancer mortality between 1983 and 2012 in Korea, and conducted age-period-cohort (APC) analysis by educational level. Age-standardized mortality rates of breast cancer per 100,000 person-years were calculated. Relative index of inequality (RII) for breast cancer mortality was used as an inequality measure. APC analyses were conducted using the Web tool for APC analysis provided by the Division of Cancer Epidemiology and Genetics at the U.S. National Cancer Institute. An increasing trend in breast cancer mortality among Korean women between 1983 and 2012 was due to the increased mortality of the lower education groups (i.e., no formal education or primary education and secondary education groups), not the highest education group. The breast cancer mortality was higher in women with a tertiary education than in women with no education or a primary education during 1983-1992, and the reverse was true in 1993-2012. Consequently, RII was changed from positive to negative associations in the early 2000s. The lower education groups had the increased breast cancer mortality and significant cohort and period effects between 1983 and 2012, whereas the highest group did not. APC analysis by socioeconomic position used in this study could provide an important clue for the causes on breast cancer mortality. The long-term monitoring of socioeconomic patterning in breast cancer risk factors is urgently needed.

Causal effect of education on mortality in a quasi-experiment on 1.2 million Swedes.

Lager, Anton Carl Jonas; Torssander, Jenny

In 1949-1962, Sweden implemented a 1-y increase in compulsory schooling as a quasi-experiment. Each year, children in a number of municipalities were exposed to the reform and others were kept as controls, allowing us to test the hypothesis that education is causally related to mortality. We studied all children born between 1943 and 1955, in 900 Swedish municipalities, with control for birth-cohort and area differences. Primary outcome measures are all-cause and cause-specific mortality until the end of 2007. The analyses include 1,247,867 individuals, of whom 92,351 died. We found lower all-cause mortality risk in the experimental group after age 40 [hazard ratio (HR) = 0.96, 95% confidence interval (CI) 0.93-0.99] but not before (HR = 1.03, 95% CI 0.98-1.07) or during the whole follow-up (HR = 0.98, 95% CI 0.95-1.01). After age 40, the experimental group had lower mortality from overall cancer, lung cancer, and accidents. In addition, exposed women had lower mortality from ischemic heart disease, and exposed men lower mortality from overall external causes. In analyses stratified for final educational level, we found lower mortality in the experimental group within the strata that settled for compulsory schooling only (HR = 0.94, 95% CI 0.89-0.99) and compulsory schooling plus vocational training (HR = 0.92, 95% CI 0.88-0.97). Thus, the experimental group had lower mortality from causes known to be related to education. Lower mortality in the experimental group was also found among the least educated, a group that clearly benefited from the reform in terms of educational length. However, all estimates are small and there was no evident impact of the reform on all-cause mortality in all ages.

We estimated the influenza mortality burden in adults 60 years of age and older in the Netherlands in terms of years of life lost, taking into account competing mortality risks. Weekly laboratory surveillance data for influenza and other respiratory pathogens and weekly extreme temperature served as covariates in Poisson regression models fitted to weekly age-group specific mortality data for the period 1999/2000 through 2012/13. Burden for age-groups 60-64 through 85-89 years was computed as years of life lost before age 90 (YLL90) using restricted mean lifetimes survival analysis and accounting for competing risks. Influenza-attributable mortality burden was greatest for persons aged 80-84 years, at 914 YLL90 per 100,000 persons (95% uncertainty interval:867, 963), followed by 85-89 years (787 YLL90/100,000; 95% uncertainty interval:741, 834). Ignoring competing mortality risks in the computation of influenza-attributable YLL90 would lead to substantial over-estimation of burden, from 3.5% for 60-64 years to 82% for persons aged 80-89 years at death. Failure to account for competing mortality risks has implications for accuracy of disease burden estimates, especially among persons aged 80 years and older. As the mortality burden borne by the elderly is notably high, prevention initiatives may benefit from being redesigned to more effectively prevent infection in the oldest age-groups. © The Author(s) 2018.

Breast cancer is the most commonly diagnosed cancer worldwide. Breast cancer is also the second leading cause of cancer death among women in the United States after lung cancer with over 40,000 breast cancer deaths occurring each year. The purpose of this research was to determine the all-cause mortality of applicants diagnosed with breast cancer currently or at some time in the past. Life insurance applicants with reported breast cancer were extracted from data covering United States residents between November 2007 and November 2014. Information about these applicants was matched to the Social Security Death Master (SSDMF) file for deaths occurring from 2007 to 2011 and to another commercially available death source file (Other Death Source, ODS) for deaths occurring from 2007 to 2014 to determine vital status. If there was a death from the other death source, then the SSDMF was searched to verify the death. The study had approximately 561,000 person-years of exposure. Actual-to-expected (A/E) mortality ratios were calculated using the Society of Actuaries 2008 Valuation Basic Table (2008VBT), select and ultimate table (age last birthday) and the 2010 US population as expected mortality ratios. Since the A/Es presented in this paper were known to be an underestimate due to the exclusion of the recent SSDMF deaths, comparative analysis of the mortality ratios was done. Since there was no smoking status information in this study, all expected bases were not smoker distinct. Overall, the 35-44 age group had 6.3 times the relative mortality ratio than those in the 65-75 age group. The relative mortality ratio for the 35-44 age group applicants, when cancer severity was accounted for in combination with 3 or more nodes of cancer involvement, was 29.3 times that when compared to those in the 65-75 age group having localized cancer, where no nodes are involved. The 35-44 age group applicants who were diagnosed with cancer within the last year had over 10-fold increase in relative mortality ratios compared to the 65-75 age group, who were over 10 years from diagnosis. Taking the severity of cancer along with time from diagnosis showed over a 12 times relative mortality ratio between the low rate of over 10 years from diagnosis and localized involvement to those diagnosed within the last year having 3 or more nodes with cancer. Applicant age, time since diagnosis and cancer severity were the most significant variables to predict the relative mortality ratios.

To describe and analyze the charecteristics and trends of liver cancer mortality during the past fifty years in Qidong, China. Retrospective mortality survey was conducted to get the data on liver cancer death in the period of 1958-1971, and the data from 1972 to 2007 were obtained from the records of cancer registration in Qidong. The crude mortality rate (CR) of liver cancer, and age-standardized rate by Chinese population (CASR) and by world population (WASR) were calculated and analyzed. The total percent changes (PC) and annual percent changes (APC) were used for evaluating the increasing trends of the mortality. The sex-specific rate, age-specific rate, truncated rate of the age group 35 - 64, cumulative rate of the age group 0-74, cumulative risk, period-rate, and the rate for age-birth cohort were compared. The natural death rate in Qidong residents for the past five-decade period experienced a wave interval of 8.62‰ in 1958 down to 5.37‰ in 1979, and up to 7.75‰ in 2007. The mortality rate for all-site cancers was increased from 56.69 per 100, 000 to 234.97 per 100, 000. The mortality rate of liver cancer, being 20.45 per 100, 100 in 1958 was increased to 49.04 per 100, 000 in 1972, and up to 69.29 per 100, 000 in 2007. According to the registration data of 1972 - 2007, the death from liver cancer was accounted for 34.88% of all deaths due to cancers, with a CR of 58.86 per 100, 000, CASR of 38.36 per 100, 000, and WASR, 49.37 Per 100, 000 in Qidong. The truncated rate for the age group 35 - 64 was 117.08 per 100, 000, and the cumulative rate for the age group 0-74 and the cumulative risk were 5.15% and 5.02%, respectively. The CRs for males was 90.52 per 100, 000 and for females was 27.93 per 100, 000, with a sex ratio of 3.24:1. For the period of 1972 - 2007, the PC for CR was 49.71%, and APC was +1.41%, showing an increasing variation tendency. The APCs for CASR and WASR, however, were decreasing, with a percentage of -1.11%, and -0.84%, respectively. The age-specific mortality rates by period showed a decreasing trend for those under age of 44. Moreover, age-birth cohort analysis showed a more rapid lowering mortality in the age groups 35-, 30-, 25-, and 15-, that is, those born after 1950's. Liver cancer remains the leading death cause due to cancers in Qidong, with a continuing higher crude mortality rate. Yet the age-standardized mortality rate has presented a declining posture. The liver cancer mortality in young people in Qidong demonstrates a continuously falling trend. The campaign for the control of liver cancer in Qidong has achieved initial success.

Traumatic brain injury (TBI) is a significant global public health problem, but has received minimal attention from researchers and policy-makers in low- and middle-income countries (LMICs). Epidemiological evidence of TBI morbidity and mortality is absent at the national level for most LMICs, including China. Using data from China's Disease Surveillance Points (DSPs) system, we conducted a population-based longitudinal analysis to examine TBI mortality, and mortality differences by sex, age group, location (urban/rural), and external cause of injury, from 1 January 2006 to 31 December 2013 in China. Mortality data came from the national DSPs system of China, which has coded deaths using the International Classification of Diseases-10th Revision (ICD-10) since 2004. Crude and age-standardized mortality with 95% CIs were estimated using the census population in 2010 as a reference population. The Cochran-Armitage trend test was used to examine the significance of trends in mortality from 2006 to 2013. Negative binomial models were used to examine the associations of TBI mortality with location, sex, and age group. Subgroup analysis was performed by external cause of TBI. We found the following: (1) Age-adjusted TBI mortality increased from 13.23 per 100,000 population in 2006 to 17.06 per 100,000 population in 2008 and then began to fall slightly. In 2013, age-adjusted TBI mortality was 12.99 per 100,000 population (SE = 0.13). (2) Compared to females and urban residents, males and rural residents had higher TBI mortality risk, with adjusted mortality rate ratios of 2.57 and 1.71, respectively. TBI mortality increased substantially with older age. (3) Motor vehicle crashes and falls were the 2 leading causes of TBI mortality between 2006 and 2013. TBI deaths from motor vehicle crashes in children aged 0-14 years and adults aged 65 years and older were most often in pedestrians, and motorcyclists were the first or second leading category of road user for the other age groups. (4) TBI mortality attributed to motor vehicle crashes increased for pedestrians and motorcyclists in all 7 age groups from 2006 to 2013. Our analysis was limited by the availability and quality of data in the DSPs dataset, including lack of injury-related socio-economic factors, policy factors, and individual and behavioral factors. The dataset also may be incomplete in TBI death recording or contain misclassification of mortality data. TBI constitutes a serious public health threat in China. Further studies should explore the reasons for the particularly high risk of TBI mortality among particular populations, as well as the reasons for recent increases in certain subgroups, and should develop solutions to address these challenges. Interventions proven to work in other cultures should be introduced and implemented nationwide. Examples of these in the domain of motor vehicle crashes include policy change and enforcement of laws concerning helmet use for motorcyclists and bicyclists, car seat and booster seat use for child motor vehicle passengers, speed limit and drunk driving laws, and alcohol ignition interlock use. Examples to prevent falls, especially among elderly individuals, include exercise programs, home modification to reduce fall risk, and multifaceted interventions to prevent falls in all age groups.

Several studies have investigated the relationship between specific occupations and suicide mortality, as suicide rates differ by profession. The aim of this study was to investigate suicide mortality ratios across broad occupational groups in Greece for both sexes in the period 2000-2009. Data of suicide deaths were retrieved from the Hellenic Statistical Authority and comparative mortality ratios were calculated. Occupational classification was based on the International Classification of Occupations (ISCO-88) and the coding for Intentional self-harm (X60-X84) was based on the international classification of diseases (ICD-10). Male dominant occupations, mainly armed forces, skilled farmers and elementary workers, and female high-skilled occupations were seen as high risk groups for suicide in a period of 10 years. The age-productive group of 30-39 years in Greek male elementary workers and the 50-59 age-productive group of Greek professional women proved to have the most elevated number of suicide deaths. Further research is needed into the work-related stressors of occupations with high suicide mortality risk and focused suicide prevention strategies should be applied within vulnerable working age populations.

Is Acute Myocardial Infarction Disappearing?

Following a peak in the mid 1960s, there has been a steady decline in coronary heart disease (CHD) mortality in the United States of 2.8%/y to 5.1%/y.1,2 This shift in mortality patterns is most dramatic in the age-adjusted rates. Age adjustment compensates for the transition of CHD in older age groups and the increase in the aged population. The absolute number of total CHD deaths showed little change until recently (Figure 1). Life expectancy of adults dramatically increased, largely as a result of these improved CHD outcomes.3 However, the reduction in mortality was not associated with a decline in hospital morbidity as CHD was pushed into the older age groups.1 Prevalence actually increased with more individuals diagnosed, treated, and surviving.1 CHD hospitalizations for those >65 years of age increased from 1965 to 2000 while declining in younger age groups.1 PMID:20212286

Coherent mortality forecasts for a group of populations: An extension of the Lee-Carter method

Mortality patterns and trajectories in closely related populations are likely to be similar in some respects, and differences are unlikely to increase in the long run. It should therefore be possible to improve the mortality forecasts for individual countries by taking into account the patterns in a larger group. Using the Human Mortality Database, we apply the Lee-Carter model to a group of populations, allowing each its own age pattern and level of mortality but imposing shared rates of change by age. Our forecasts also allow divergent patterns to continue for a while before tapering off. We forecast greater longevity gains for the US and lesser ones for Japan relative to separate forecasts.

There are limited validated methods to ascertain comorbidities for risk adjustment in ambulatory populations of patients with diabetes using administrative health-care databases. The objective was to examine the ability of the Johns Hopkins' Aggregated Diagnosis Groups to predict mortality in population-based ambulatory samples of both incident and prevalent subjects with diabetes. Retrospective cohorts constructed using population-based administrative data. The incident cohort consisted of all 346,297 subjects diagnosed with diabetes between 1 April 2004 and 31 March 2008. The prevalent cohort consisted of all 879,849 subjects with pre-existing diabetes on 1 January, 2007. The outcome was death within 1 year of the subject's index date. A logistic regression model consisting of age, sex and indicator variables for 22 of the 32 Johns Hopkins' Aggregated Diagnosis Group categories had excellent discrimination for predicting mortality in incident diabetes patients: the c-statistic was 0.87 in an independent validation sample. A similar model had excellent discrimination for predicting mortality in prevalent diabetes patients: the c-statistic was 0.84 in an independent validation sample. Both models demonstrated very good calibration, denoting good agreement between observed and predicted mortality across the range of predicted mortality in which the large majority of subjects lay. For comparative purposes, regression models incorporating the Charlson comorbidity index, age and sex, age and sex, and age alone had poorer discrimination than the model that incorporated the Johns Hopkins' Aggregated Diagnosis Groups. Logistical regression models using age, sex and the John Hopkins' Aggregated Diagnosis Groups were able to accurately predict 1-year mortality in population-based samples of patients with diabetes. © 2011 The Authors.

Logistic regression models that incorporated age, sex, and indicator variables for the Johns Hopkins' Aggregated Diagnosis Groups (ADGs) categories have been shown to accurately predict all-cause mortality in adults. To develop 2 different point-scoring systems using the ADGs. The Mortality Risk Score (MRS) collapses age, sex, and the ADGs to a single summary score that predicts the annual risk of all-cause death in adults. The ADG Score derives weights for the individual ADG diagnosis groups. : Retrospective cohort constructed using population-based administrative data. All 10,498,413 residents of Ontario, Canada, between the age of 20 and 100 years who were alive on their birthday in 2007, participated in this study. Participants were randomly divided into derivation and validation samples. : Death within 1 year. In the derivation cohort, the MRS ranged from -21 to 139 (median value 29, IQR 17 to 44). In the validation group, a logistic regression model with the MRS as the sole predictor significantly predicted the risk of 1-year mortality with a c-statistic of 0.917. A regression model with age, sex, and the ADG Score has similar performance. Both methods accurately predicted the risk of 1-year mortality across the 20 vigintiles of risk. The MRS combined values for a person's age, sex, and the John Hopkins ADGs to accurately predict 1-year mortality in adults. The ADG Score is a weighted score representing the presence or absence of the 32 ADG diagnosis groups. These scores will facilitate health services researchers conducting risk adjustment using administrative health care databases.

To analyze the trend in socioeconomic inequalities in all-cause mortality in Barcelona from 1983 to 2004. We performed an ecological study of trends over 4 cross-sections (1983-1988, 1989-1994, 1995-1999 and 2000-2004), with the basic health area (BHA) as the unit of analysis. The study population consisted of men and women aged 20 years or more living in Barcelona. The information sources were the mortality registry, the municipal census and the census of inhabitants and dwellings. The age- and sex-specific mortality rate (ASMR) for all causes was used as the dependent variable. As the independent variable, a composite index of socioeconomic deprivation of the BHA was calculated; BHAs were grouped in quartiles according to the values on the index. Poisson models were adjusted to estimate the relative risk of mortality from all causes in the 4 groups of BHA, stratified by age groups and sex. In all the study periods, inequalities in mortality were found, depending on the BHA of residence, both for men and for women: the ASMR of the most deprived BHAs were greater than those of less deprived BHA, and were greater among men than among women. Likewise, relative risks in the youngest age groups were higher than in the oldest age groups. However, from the second to fourth study periods, inequalities decreased in absolute and relative terms, especially among men. Inequalities in mortality persist in BHA in Barcelona but have decreased over the last 2 decades. Public policies should take this information into account when tackling inequalities among BHA.

A model for spatial variations in life expectancy; mortality in Chinese regions in 2000.

PubMed

Congdon, Peter

2007-05-02

Life expectancy in China has been improving markedly but health gains have been uneven and there is inequality in survival chances between regions and in rural as against urban areas. This paper applies a statistical modelling approach to mortality data collected in conjunction with the 2000 Census to formally assess spatial mortality contrasts in China. The modelling approach provides interpretable summary parameters (e.g. the relative mortality risk in rural as against urban areas) and is more parsimonious in terms of parameters than the conventional life table model. Predictive fit is assessed both globally and at the level of individual five year age groups. A proportional model (age and area effects independent) has a worse fit than one allowing age-area interactions following a bilinear form. The best fit is obtained by allowing for child and oldest age mortality rates to vary spatially. There is evidence that age (21 age groups) and area (31 Chinese administrative divisions) are not proportional (i.e. independent) mortality risk factors. In fact, spatial contrasts are greatest at young ages. There is a pronounced rural survival disadvantage, and large differences in life expectancy between provinces.

High on-farm mortality is associated with lower financial return of production and poor animal health and welfare. Understanding the reasons for on-farm mortality and related risk factors allows focus on specific prevention measures. This retrospective cohort study used cattle registry data from the years 2013 and 2014, collected from cattle from all Estonian cow-calf beef herds. The dataset contained 78,605 animal records from 1321 farms in total. Including unassisted deaths and euthanasia (2199 in total) the on-farm mortality rate was 2.14 per 100 animal-years. Across all age groups of both sexes the mortality rate (MR) was highest for bull calves up to three months old (MR=7.78 per 100 animal-years, 95% CI 6.97; 8.68) followed by that for heifer calves (MR=6.21 per 100 animal-years, 95% CI 5.49; 7.02). For female cattle the mortality risk declined after three months of age but increased again among animals over 18 months. The reason for death stated by the farmers was analysed for cattle under animal performance testing. Other/unknown reasons, trauma and accidents, as well as metabolic and digestive disorders, formed the three most commonly reported reasons for death in cattle of all age groups. Weibull proportional hazard models with farm frailty effects were applied in three age categories (calves up to three months, youngstock from three to 18 months and cattle aged over 18 months) to identify factors associated with the risk of mortality. Male sex was associated with increased risk of mortality in cattle up to 18 months of age. No difference between breeds was found for cattle up to 18 months of age. Beef cattle breeds rarely represented or dairy breeds (breed category 'Other') had the highest mortality hazard (HR=1.41, 95% CI 1.11; 1.78) compared to Hereford. The hazard of mortality generally increased with herd size for calves, young stock and older bulls. In female cattle over 18 months of age there was no difference in mortality hazard over herd size categories. Herd location was controlled in the models and regional differences in mortality hazard were found. Common to all age groups, calving season was associated with increased risk of mortality.

A 2001 study on geriatric trauma by trauma center (TC) status was based on 1989 Medicare data. The purpose of this study was to compare 1989 findings with a 2009 sample, and to examine patient characteristics and outcomes by TC status. From 2009 Healthcare Cost and Utilization Project Nationwide Inpatient Sample (HCUP NIS) data, we examined a geographically representative sample (n = 25,512) of injured older adults (>/= age 65) admitted to 127 TCs and non-TCs in 24 states. Data analysis included descriptive statistics for eight patient characteristics and four outcome variables (mortality, discharge disposition, length of stay, and total charges). χ(2) tests were conducted to examine differences between 1989 and 2009 for age groups, gender, and mortality. Higher percentages of patients were in older age groups in 2009, however mortality declined overall (4.8% vs 3.4%, P < .001). Consistent incremental patterns of differences were observed among TC levels for all patient characteristics and outcomes. Level I TCs admitted highest percentages of: lower age groups, males, nonwhite race, motor-vehicle related trauma, and intracranial injuries. Non-TCs admitted highest percentages of oldest age groups, comorbidities, falls, femur neck fractures, and patients requiring OR procedures. Although Level I TCs had higher lengths of stay and total charges, a higher percentage of patients were discharged home. Despite a growing number of patients in older age groups, inpatient mortality declined over two decades. Level I TCs are managing patients at highest risk for decompensation and mortality; a significant percentage of patients are going to non-TCs.

Research comparing mortality by socioeconomic status has found that inequalities are not the smallest in the Nordic countries. This is in contrast to expectations given these countries' policy focus on equity. An alternative way of studying inequality has been little used to compare inequalities across welfare states and may yield a different conclusion. We used average life expectancy lost per death as a measure of total inequality in mortality derived from death rates from the Human Mortality Database for 37 countries in 2006 that we grouped by welfare state type. We constructed a theoretical 'lowest mortality comparator country' to study, by age, why countries were not achieving the smallest inequality and the highest life expectancy. We also studied life expectancy as there is an important correlation between it and inequality. On average, Nordic countries had the highest life expectancy and smallest inequalities for men but not women. For both men and women, Nordic countries had particularly low younger age mortality contributing to smaller inequality and higher life expectancy. Although older age mortality in the Nordic countries is not the smallest. There was variation within Nordic countries with Sweden, Iceland and Norway having higher life expectancy and smaller inequalities than Denmark and Finland (for men). Our analysis suggests that the Nordic countries do have the smallest inequalities in mortality for men and for younger age groups. However, this is not the case for women. Reducing premature mortality among older age groups would increase life expectancy and reduce inequality further in Nordic countries.

Estimates of biological age based on DNA methylation patterns, often referred to as "epigenetic age", "DNAm age", have been shown to be robust biomarkers of age in humans. We previously demonstrated that independent of chronological age, epigenetic age assessed in blood predicted all-cause mortality in four human cohorts. Here, we expanded our original observation to 13 different cohorts for a total sample size of 13,089 individuals, including three racial/ethnic groups. In addition, we examined whether incorporating information on blood cell composition into the epigenetic age metrics improves their predictive power for mortality. All considered measures of epigenetic age acceleration were predictive of mortality (p≤8.2x10 -9 ) , independent of chronological age, even after adjusting for additional risk factors (p<5.4x10 -4 ) , and within the racial/ethnic groups that we examined (non-Hispanic whites, Hispanics, African Americans). Epigenetic age estimates that incorporated information on blood cell composition led to the smallest p-values for time to death (p=7.5x10 -43 ). Overall, this study a) strengthens the evidence that epigenetic age predicts all-cause mortality above and beyond chronological age and traditional risk factors, and b) demonstrates that epigenetic age estimates that incorporate information on blood cell counts lead to highly significant associations with all-cause mortality.

Mortality from asthma increased and is now declining in some countries, but little is known about these trends in South America. We aimed to assess trends in mortality from asthma in southern Brazil in children and young adults. Death certificates of 425 people in the state of Rio Grande do Sul aged between 5 and 39 years in whom asthma was reported to be the underlying cause of death during the period 1970 to 1992 were reviewed. Population data were available in 10-year age groups. Testing for trends in mortality rates was conducted using linear and log-linear regression procedures. Asthma mortality rates in the age groups 5 to 19 and 20 to 39 years ranged between 0.04 and 0.39/100,000 and 0.28 to 0.75/100,000, respectively, and were nonuniformly distributed over the study period. The mean annual increase in rate in 5- to 19-year olds was +0.01 (95% CI 0.003 to 0.016), an average annual percentage increase of +6.8% (95% CI 3% to 11%), with a total increase of 352% between 1970 and 1992. This increase was not due to a shift in labeling from bronchitis to asthma. In the 20 to 39-year age group, asthma and bronchitis mortality rates showed no trend to increase or decrease. Asthma mortality in southern Brazil is low, but rose significantly between 1970 and 1992 in the 5 to 19-year age group. This trend differs from that found in other states of Brazil and several other Latin American countries. Reasons for this difference remain unclear.

The aim was to assess time trend of mortality with musculoskeletal disorders (MSD) as underlying cause of death in Sweden from 1997 to 2013. We obtained data on MSD as underlying cause of death across age and sex groups from the National Board of Health and Welfare's Cause of Death Register. Age-standardized mortality rates per million population for all MSD, its six major subgroups, and all other ICD-10 (International Classification of Disease) chapters were calculated. We computed the average annual percent change (AAPC) in the mortality rates across age/sex groups using joinpoint regression analysis by fitting a regression line to the natural logarithm of the age-standardized mortality rates and calendar year as a predictor. There were a total of 7 976 deaths (0.5% of all causes deaths) with MSD as the underlying cause of death (32.5% of these deaths caused by rheumatoid arthritis [RA]). The overall age-standardized mortality rates (95% CI) were 16.0 (15.4 to 16.7) and 24.9 (24.1 to 25.7) per million among men and women, respectively (women/men rate ratio 1.55; 95%CI 1.47 to 1.63). On average, mortality rate declined by 2.3% per year and only circulatory system mortality had a more favourable decline than mortality with MSD as underlying cause. Among MSD the highest decline was observed in RA (3.7% per year) during study period. Across age groups, while there were generally stable or declining trends, spondylopathies and osteoporosis mortality among people ≥ 75 years increased by 2 and 1.5% per year, respectively. In overall, mortality with MSD as underlying cause has declined in Sweden over last two decades, with the highest decline for RA. However, there are variations across MSD subgroups which warrants further investigations.

The Muslims of Aligarh city are predominantly Sunnis, although there are also a considerable number of Shias. Among the Sunnis, approximately a quarter belong to Syed, Sheikh, Moghal and Pathan groups, and three-quarters belong to various lower biradaris. In the present study, 304 women attending the Primary Health Centre of the J. N. Medical College and Hospital, Aligarh Muslim University, Uttar Pradesh, were surveyed and the following recorded among Muslim women of high-rank (Ashraf) and low-rank (Ajlaf) castes: incidence of marriage, age of the mother at the time of marriage, present age of the mother, abortions, still births, pre-reproductive mortality and overall mortality. The Ashraf are comprised of the Sheikh, Syed and Pathan, whereas the Ajlafs have Qureshi, Saifi and Ansari biradaris. Maternal age was scored as above and below 45 years in each biradari. Significant effects of maternal age were seen on mortality of offspring, whereas populations did not show consistent differences, except when Ashrafs and Ajlafs were considered separately. The results show higher mortality and abortions for various groups. This may be due to various biological and socio-cultural factors, including hidden inbreeding in the remote past.

Background To more efficiently reduce social inequalities in mortality, it is important to establish which causes of death contribute the most to socioeconomic mortality differentials. Few studies have investigated which diseases contribute to existing socioeconomic mortality differences in specific age groups and none were in samples of the whole population, where selection bias is minimized. The aim of the present study was to determine which causes of death contribute the most to social inequalities in mortality in each age group in the whole population of Scania, Sweden. Methods Data from LOMAS (Longitudinal Multilevel Analysis in Skåne) were used to estimate 12-year follow-up mortality rates across levels of socioeconomic position (SEP) and workforce participation in 975,938 men and women aged 0 to 80 years, during 1991–2002. Results The results generally showed increasing absolute mortality differences between those holding manual and non-manual occupations with increasing age, while there were inverted u-shaped associations when using relative inequality measures. Cardiovascular diseases (CVD) contributed to 52% of the male socioeconomic difference in overall mortality, cancer to 18%, external causes to 4% and psychiatric disorders to 3%. The corresponding contributions in women were 55%, 21%, 2% and 3%. Additionally, those outside the workforce (i.e., students, housewives, disability pensioners, and the unemployed) showed a strongly increased risk of future mortality in all age groups compared to those inside the workforce. Even though coronary heart disease (CHD) played a major contributing role to the mortality differences seen, stroke and other types of cardiovascular diseases also made substantial contributions. Furthermore, while the most common types of cancers made substantial contributions to the socioeconomic mortality differences, in some age groups more than half of the differences in cancer mortality could be attributed to rarer cancers. Conclusion CHD made a major contribution to the socioeconomic differences in overall mortality. However, there were also important contributions from diseases with less well understood mechanistic links with SEP such as stroke and less-common cancers. Thus, an increased understanding of the mechanisms connecting SEP with more rare causes of disease might be important to be able to more successfully intervene on socioeconomic differences in health.

Determine the relationship between albumin levels and all-cause mortality in life insurance applicants. By use of the Social Security Death Master File, mortality was determined in 1,704,566 insurance applicants for whom blood samples were submitted to Clinical Reference Laboratory. There were 53,211 deaths observed in this healthy adult population during a median follow-up of 12 years. Results were stratified by 6 age-sex groups: females: ages 20 to 49, 50 to 69 and 70+; and males: ages 20 to 49, 50 to 69 and 70+. The middle 50% of albumin values specific to each group was used as the reference band for that group. The mortality in bands representing other percentiles of albumin values higher and lower than the middle 50% were compared to the mortality in the reference band for each age-sex group. The highest percentile bands represent the lowest albumin values. Relative risk exceeded 150% of each age- and sex-specific reference band for all groups between the 90th and 95th percentile of albumin values. This translates into 150% risk thresholds at approximately 3.8 mg/dL for all females and for males 70+, and 4.1 mg/dL for males ages 20 to 69. Conversely, the highest 25% of albumin values were associated with approximately a 20% reduction in risk in males and a variable 10% reduction in risk in females when compared to the middle 50% of albumin values. Excluding those with total cholesterol < or = 160 mg/dL, or with AST, GGT or alkaline phosphatase elevations, had little impact on relative risk except at the lowest 0.5% of albumin values. When stratified by age and sex, albumin discriminated between all-cause mortality risks in healthy adults at all ages and across a wide range of values independent of other laboratory tests.

Objective: To understand the status and trend of the mortality rate of falls in different gender, age groups and provinces in China from 1990 to 2015, to explore the number of subgroups of different trends in all provinces, and to determine the different trajectory of subgroups. Methods: Using the mortality rate of falls in China from 1990 to 2015 from the Global Disease Burden 2015 (data covers 31 provinces, autonomous regions, municipalities, as well as Hong Kong and Macau Special Administrative Regions, excluding Taiwan Province) to describe the status of the mortality rate of falls in different gender, age group and provinces in China 2015 and to calculate the corresponding relative change. Using log linear model to calculate the annual percent changes from 1990 to 2015. The number of subgroups and corresponding characteristics of different trajectories were analyzed by trajectory model to analyze with four indicators, P value of the coefficient of independent variables with different orders in all subgroups, Bayesian information criterion, log Bayes factor and average posterior probability. Results: In 2015, the age standardized mortality rate of falls in China was 8.38/100 000 (95 %UI : 5.54/100 000-9.30/100 000), which was higher in men (10.81/100 000, 95 %UI : 6.58/100 000-12.14/100 000) than that in women (5.84/100 000,95 %UI : 3.41/100 000-6.62/100 000), and in the elderly aged 70-year-old and above (60.50/100 000, 95 %UI : 38.36/100 000-67.75/100 000) than that in other age groups. From 1990 to 2015, there was no obvious change in the age standardized mortality rate of falls in total population, men and women with average percent change about 0.37 (95 %UI : -0.08-0.83), 0.45 (95 %UI : 0.05-0.84) and 0.31 (95 %UI : -0.26-0.87) respectively, but a significant decrease and increase could be seen in children under 15-year-old, especially under 5-year-old with average percent change about -4.07 (95 %UI : -5.62--2.51), and the elderly aged 70-year-old and above with average percent change about 1.89 (95 %UI : 1.42-2.37) respectively. Four types of trajectories could be categorized for different trends of age standardized mortality rate of falls in all provinces. The first group had the lowest fall mortality with a downward trend. The fall mortality was close in the second and third group but with different change tendency, a decreasing propensity in the former and an increasing one in the latter. The fourth group had the highest fall morality with obvious fluctuation. Conclusion: There was no significant change in the age standardized mortality rate of falls in China from 1990 to 2015. However, the trend of age standardized mortality rate of falls varied in different age and provinces during the same period of time.

This article presents age-specific mortality rates of children for selected causes of accidents and assault using the National Statistics Socio-economic Classification (NS-SEC). The study is an analysis of the social inequalities in fatal childhood accidents and assault at the start of the 21st century. It aims to identify the causes and age groups for which these inequalities are the widest. In order to classify children by NS-SEC, the most advantaged class of the biological or adoptive parents was used. Death registrations provided the number of deaths from accidents and assault for children aged from 28 days to 15 years, in England and Wales, between 2001 and 2003. The population of children by NS-SEC and age group was obtained from the 2001 Census. Age-specific mortality rates were estimated. Inequalities were measured using socio-economic gradients in mortality. There were wide social inequalities in fatal accidents and assaults for children aged between 28 days and 15 years. The overall mortality rate in the routine class was 64 per million children aged up to 15, 4.5 times the rate of children with parents in the higher managerial and professional class. The greatest inequalities in accidental mortality for children in that age group were observed for fire and pedestrian accidents, followed by accidental suffocation. Infants at least 28 days but less than one year were subject to the widest inequalities of all age groups in fatal accidents and assault. The highest mortality rate in this study resulted from assault on babies whose parents could not be classified by occupation. Pedestrian and other transport accidents were the greatest causes of death for children between 5 and 15 years old. Inequalities were much larger for pedestrian than for other transport accidents for children aged 14 years and under. The leading cause of death for children aged less than five years was suffocation, followed by drowning and exposure to fire/hot substances. In that age group, the risk of death from exposure to fire was significantly higher for children whose parents could not be classified by occupation. Substantial social inequalities in childhood mortality from accidents and assault existed in 2001-03. Reducing the large inequalities between the most advantaged class and the most disadvantaged group in the non-occupied category, would make a substantial impact on childhood deaths from accidents and assaults. If the mortality rates in the latter group were the same as in the most advantaged managerial and professional class, deaths of infants of at least 28 days but less than one year, from assault would be reduced by 62 per cent. Deaths from fire, accidental suffocation and pedestrian accidents in the under fives would be reduced by 50 per cent, 25 per cent and 28 per cent respectively. Deaths in pedestrian and transport accidents for children aged 5-15 would be reduced by 25 per cent and 16 per cent respectively.

Objective: To estimate the incidence and mortality of female breast cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR), and to provide support data for breast cancer prevention and control in China. Methods: There were 449 cancer registries submitting female breast cancer incidence and deaths data occurred in 2014 to NCCR. After evaluating the data quality, 339 registries' data were accepted for analysis and stratified by areas (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of female breast cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas) in 2014. The morphology verified cases (MV%) accounted for 87.42% and 0.59% of incident cases were identified through death certifications only (DCO%), with mortality to incidence ratio of 0.24. The estimates of new breast cancer cases were about 278 900 in China in 2014, accounting for 16.51% of all new cases in female. The crude incidence rate, age-standardized rate of incidence by Chinese standard population (ASRIC), and age-standardized rate of incidence by world standard population (ASRIW) of breast cancer were 41.82/100 000, 30.69/100 000, and 28.77/100 000, respectively, with a cumulative incidence rate (0-74 age years old) of 3.12%. The crude incidence rates and ASRIC in urban areas were 49.94 per 100 000 and 34.85 per 100 000, respectively, whereas those were 31.72 per 100 000 and 24.89 per 100 000 in rural areas. The estimates of breast cancer deaths were about 66 000 in China in 2014, accounting for 7.82% of all the cancer-related deaths in female. The crude mortality rate, age-standardized rate of mortality by Chinese standard population(ASRMC) and age-standardized rate of mortality by world standard population (ASRMW) of breast cancer were 9.90/100 000, 6.53/100 000, and 6.35/100 000, respectively, with a cumulative mortality rate of 0.69%. The crude mortality rates and ASRMC in urban areas were 11.48 per 100 000 and 7.04 per 100 000, respectively, whereas those were 7.93 per 100 000 and 5.79 per 100 000 in rural areas. The incidence and mortality rates of breast cancer were higher in areas than those in rural areas. The age-specific incidence rates of breast cancer increased greatly after 20 years old and peaked at the age group of 55-60. The age-specific mortality rates increased rapidly with age, particularly after 25 years old. They remained at a relative stable level from 55 to 65 years of age, and then increased dramatically and peaked in the age group of 85 and above. Conclusions: Breast cancer is still one of the most common malignant tumor threatening to famale health in China. The disease is more prevalent in urban areas at the age group of 55-60. Comprehensive prevention and control strategies referring to local status and age groups should be carried out to reduce the burden of breast cancer.

The last published figures have shown geographical variations in mortality with respect to female breast cancer in European countries. However, national health policies need a dynamic image of the geographical variations within the country. The aim of this paper was to describe the spatial distribution of age-specific mortality rates from female breast cancer in the municipalities of Andalusia (southern Spain) and to analyze its evolution over time from 1981 to 2012. An ecological study was devised. Two spatio-temporal hierarchical Bayesian models were estimated. One of these was used to estimate the age-specific mortality rate for each municipality, together with its time trends, and the other was used to estimate the age-specific rate ratio compared with Spain as a whole. The results showed that 98% of the municipalities exhibited a decreasing or a flat mortality trend for all the age groups. In 2012, the geographical variability of the age-specific mortality rates was small, especially for population groups below 65. In addition, more than 96.6% of the municipalities showed an age-specific mortality rate similar to the corresponding rate for Spain, and there were no identified significant clusters. This information will contribute towards a reflection on the past, present and future of breast cancer outcomes in Andalusia.

[The changing sex differences in life expectancy in Spain (1980-2012): decomposition by age and cause].

García González, Juan Manuel; Grande, Rafael

To calculate and analyse the contributions of changes in mortality by age groups and selected causes of death to sex differences in life expectancy at birth in Spain from 1980 to 2012. Cross-sectional study with three time points (1980, 1995, and 2012). We used data from Human Cause-of-Death Database and Human Mortality Database. We use a decomposition method of the differences in life expectancy and gender differences in life expectancy from changes in mortality by 5-year age groups and causes of death between women and men. From 1980 to 1995, the lower mortality of women from 25 years old, and the differences in mortality by HIV/AIDS, lung cancer, and chronic obstructive pulmonary diseases contributed to the gap increase. From 1995 to 2012, greatest improvement in mortality of males under 74 years of age, and in improving male mortality from HIV/AIDS, acute myocardial infarction and traffic accidents contributed to the narrowing. The difference in life expectancy at birth between men and women has decreased since 1995 due to a greater improvement in mortality from causes of death associated with risky behaviours and habits of the working age male population.

Structured settlement annuities, part 2: mortality experience 1967--95 and the estimation of life expectancy in the presence of excess mortality.

PubMed

Singer, R B; Schmidt, C J

2000-01-01

the mortality experience for structured settlement (SS) annuitants issued both standard (Std) and substandard (SStd) has been reported twice previously by the Society of Actuaries (SOA), but the 1995 mortality described here has not previously been published. We describe in detail the 1995 SS mortality, and we also discuss the methodology of calculating life expectancy (e), contrasting three different life-table models. With SOA permission, we present in four tables the unpublished results of its 1995 SS mortality experience by Std and SStd issue, sex, and a combination of 8 age and 6 duration groups. Overall results on mortality expected from the 1983a Individual Annuity Table showed a mortality ratio (MR) of about 140% for Std cases and about 650% for all SStd cases. Life expectancy in a group with excess mortality may be computed by either adding the decimal excess death rate (EDR) to q' for each year of attained age to age 109 or multiplying q' by the decimal MR for each year to age 109. An example is given for men age 60 with localized prostate cancer; annual EDRs from a large published cancer study are used at duration 0-24 years, and the last EDR is assumed constant to age 109. This value of e is compared with e from constant initial values of EDR or MR after the first year. Interrelations of age, sex, e, and EDR and MR are discussed and illustrated with tabular data. It is shown that a constant MR for life-table calculation of e consistently overestimates projected annual mortality at older attained ages and underestimates e. The EDR method, approved for reserve calculations, is also recommended for use in underwriting conversion tables.

The aim of this study was to assess the long-term outcomes of aortic valve replacement (AVR) with either mechanical or bioprosthetic valves according to age at operation.Methods and Results:A total of 1,002 patients (527 mechanical valves and 475 bioprosthetic valves) undergoing first-time AVR were categorized according to age at operation: group Y, age <60 years; group M, age 60-69 years; and group O, age ≥70 years). Outcomes were compared on propensity score analysis (adjusted for 28 variables). Hazard ratio (HR) was calculated using the Cox regression model with adjustment for propensity score with bioprosthetic valve as a reference (HR=1). There were no significant differences in overall mortality between mechanical and bioprosthetic valves for all age groups. Valve-related mortality was significantly higher for mechanical valves in group O (HR, 2.53; P=0.02). Reoperation rate was significantly lower for mechanical valves in group Y (HR, 0.16; P<0.01) and group M (no events for mechanical valves). Although the rate of thromboembolic events was higher in mechanical valves in group Y (no events for tissue valves) and group M (HR, 9.05; P=0.03), there were no significant differences in bleeding events between all age groups. The type of prosthetic valve used in AVR does not significantly influence overall mortality.

Background Several studies have investigated the relationship between specific occupations and suicide mortality, as suicide rates differ by profession. The aim of this study was to investigate suicide mortality ratios across broad occupational groups in Greece for both sexes in the period 2000–2009. Methods Data of suicide deaths were retrieved from the Hellenic Statistical Authority and comparative mortality ratios were calculated. Occupational classification was based on the International Classification of Occupations (ISCO-88) and the coding for Intentional self-harm (X60–X84) was based on the international classification of diseases (ICD-10). Results Male dominant occupations, mainly armed forces, skilled farmers and elementary workers, and female high-skilled occupations were seen as high risk groups for suicide in a period of 10 years. The age-productive group of 30–39 years in Greek male elementary workers and the 50–59 age-productive group of Greek professional women proved to have the most elevated number of suicide deaths. Conclusion Further research is needed into the work-related stressors of occupations with high suicide mortality risk and focused suicide prevention strategies should be applied within vulnerable working age populations.

Our aims were to determine acute myocardial infarction (AMI) incidence and mortality rates, and population and in-hospital case-fatality in the population older than 74 years; variability in clinical characteristics and AMI management of hospitalized patients, and changes in the incidence and mortality rates, case-fatality, and management by age groups from 1996 to 1997 and 2007 to 2008. A population-based AMI registry in Girona (Catalonia, Spain) including individuals with suspected AMI older than 34 years. The incidence rate increased with age from 169 and 28 cases/100 000 per year in the group aged 35 to 64 years to 2306 and 1384 cases/100 000 per year in the group aged 85 to 94 years, in men and women, respectively. Population case-fatality also increased with age, from 19% in the group aged 35 to 64 years to 84% in the group aged 85 to 94 years. A lower population case-fatality was observed in the second period, mainly explained by a lower in-hospital case-fatality. The use of invasive procedures and effective drugs decreased with age but increased in the second period in all ages up to 84 years. Acute myocardial infarction incidence, mortality, and case-fatality increased exponentially with age. There is still a gap in the use of invasive procedures and effective drugs between younger and older patients. Copyright © 2017 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Both low socioeconomic status (SES) and diabetes mellitus (DM) are important risk factors for mortality. However, little is known about their combined effects and relative contribution to the mortality risk.From a nationwide cohort provided by the National Health Insurance Service in Korea, 153,075 subjects who were over 30 years of age from 2003 to 2004 were followed-up until 2010. The SESs of the subjects in the DM and non-DM (NDM) groups were categorized into 3 groups (highest 30% as S1, middle 40% as S2, and lowest 30% as S3) based on the subjects' income levels.During the 7.9-year follow-up, 3933 deaths occurred. When the subjects were stratified into 6 groups by their socioeconomic and diabetes status, a linearly increasing pattern of the hazard ratio (HR) of mortality from the higher SES without diabetes group (NDM-S1, as a reference) to the lower SES with diabetes group (DM-S3; HR, 2.04, 95% confidence interval (CI), 1.80-2.36) was observed (P for trend < 0.001). Notably, subjects with DM in the highest SES group (DM-S1) had a significantly higher mortality risk than did non-DM subjects in the lowest SES group (NDM-S3). This pattern was maintained in cause-specific mortality but was more prominent in cardiovascular disease (CVD) and less prominent in cancer mortality. The association was not affected by gender; however, in individuals <60 years of age, the combined effects of SES and DM on mortality were more prominent (DM-S3; HR, 3.68, 95% CI, 2.95-4.60) than in those ≥60 years of age.Low SES and DM were major determinants of mortality and synergistically increased the risks of all-cause, CVD, and cancer mortality.

OBJECTIVES To examine predictors of mortality in aging Mexican Americans (MAs) and European Americans (EAs). DESIGN Longitudinal, observational cohort study. SETTING Socioeconomically diverse neighborhoods in San Antonio, Texas. PARTICIPANTS Three hundred and ninety-four MA and 355 EA community-dwelling older adults (65+) who completed the baseline examination (1992–96) of the San Antonio Longitudinal Study of Aging (SALSA) and for whom vital status was ascertained over an average 8.2 years of follow-up. MEASUREMENTS Ethnic group was classified using a validated algorithm. Hazards ratios (HR) for mortality were estimated using Cox proportional hazards models with age, sex, ethnic group, education, income, frailty, diabetes with and without complications, comorbidity, cognition, depressive symptoms, and body mass index included as predictors in sequential models. RESULTS At baseline, MAs had higher prevalence of diabetes and frailty and lower socioeconomic status (SES) compared to EAs. The age- and sex-adjusted ethnic HR (MA vs. EA) for mortality was 1.54 (95% CI: 1.17–2.03). After adjusting for SES, the ethnic HR was no longer significant (HR = 1.16, 95% CI: 0.83–1.61). In the final model, comorbidity, diabetes with complications, depressive symptoms, and cognitive impairment were significant independent risk factors for mortality. CONCLUSION Contrary to the Hispanic paradox, MAs were at increased risk of mortality. Moreover, this ethnic disparity was largely explained by SES differences. Significant independent predictors of mortality, regardless of ethnic group, included diabetes with complications, comorbidity, depressive symptoms and cognitive impairment. Mortality reduction in older MAs requires attention to both socioeconomic disparities and disease factors. PMID:24000922

Staphylococcus aureus is known to be a leading cause of bacteremia in childhood, and is associated with severe morbidity and increased mortality. To determine developments in incidence and mortality rates, as well as risk factors associated with outcome, we analyzed data from 1971 through 2000. Nationwide registration of S. aureus bacteremia (SAB) among children and adolescents from birth to 20 years of age was performed. Data on age, sex, source of bacteremia, comorbidity and outcome were extracted from discharge records. Rates were population adjusted and risk factors for death were assessed by multivariate logistic regression analysis. During the 30-year study period, 2648 cases of SAB were reported. Incidence increased from 4.6 to 8.4 cases per 100,000 population and case-mortality rates decreased from 19.6% to 2.5% (P = 0.0001). Incidence in the infant age group (<1 year) were 10- to 17-fold greater compared with that in the other age strata and mortality rate was twice as high. Hospital-acquired infections dominated the infant group, accounting for 73.9%-91.0% versus 39.2%-50.5% in the other age groups. By multivariate analysis, pulmonary infection and endocarditis for all age groups, comorbidity for the older than 1 year, and hospital-acquired infections for the oldest group were independently associated with an increased risk of death. Mortality rates associated with SAB decreased significantly in the past 3 decades, possibly because of new and improved treatment modalities. However, incidence rates have increased significantly in the same period, underscoring that S. aureus remains an important invasive pathogen.

The objective of this study was to investigate the recent incidence and mortality trends for breast cancer in Mexican females. Data between 2000 and 2010 from the Department of Epidemiology of the Ministry of Health, and International Agency for Research on Cancer (IARC) were analyzed. Age-standardized rates (ASRs) and annual percent changes (APCs) were calculated. The absolute incidence and mortality rates of breast cancer increased: 3,726 and 4,615 in 2000 to 8,545 and 4,966 in 2010, respectively. Incidence increased over time in all age groups tested, the 60-64 age group had the highest ASR (57.4 per 100,000 women in 2010), while the 20-44 age group had the lowest ASR (12.3 in 2010). The results show that incidence of breast cancer has increased in Mexico during last one decade, especially among older women, while the downturn observed in mortality mainly reflects improved survival as a result of earlier diagnosis and better cancer treatment.

Leukemias comprise the most common group of cancers in children and adolescents. Studies conducted in other countries and Brazil have observed a decrease in their mortality.This study aimed to evaluate the trend of mortality from leukemia in children under 19 years of age in Brazil, from 1980 to 2010. This was an ecological study, using retrospective time series data from the Mortality Information System, from 1980 to 2010. Calculations of mortality rates were performed, including gross, gender-specific, and age-based. For trend analysis, linear and semi-log regression models were used. The significance level was 5%. Mortality rates for lymphoid and myeloid leukemias presented a growth trend, with the exception of lymphoid leukemia among children under 4 years of age (percentage decrease: 1.21% annually), while in the sub-group "Other types of leukemia", a downward trend was observed. Overall, mortality from leukemia tended to increase for boys and girls, especially in the age groups 10-14 years (annual percentage increase of 1.23% for males and 1.28% for females) and 15-19 years (annual percentage increase of 1.40% for males and 1.62% for females). The results for leukemia generally corroborate the results of other similar studies. A detailed analysis by subgroup of leukemia, age, and gender revealed no trends shown in other studies, thus indicating special requirements for each variable in the analysis.

Mortality attributable to tobacco among men in Sweden and other European countries: an analysis of data in a WHO report.

PubMed

Ramström, Lars; Wikmans, Tom

2014-01-01

It is well known that Swedish men have lower tobacco-related mortality than men in other European countries, but there are questions that need further investigation to what extent this is related to the specific patterns of tobacco use in Sweden, where use of snus, the Swedish low-nitrosamine oral tobacco, dominates over smoking in men but not in women. The recent WHO Global Report: Mortality Attributable to Tobacco provides a unique set of estimates of the health burden of tobacco in all countries of the world in the year 2004, and these data can help elucidating the above-mentioned questions. For Sweden and all other European Union Member States mortality data for a number of tobacco-related causes of death were extracted from the WHO Report. The size of the mortality advantage for selected causes of death in different age groups of Swedish men compared to men of the same age in Europe as a whole was calculated in terms of ratios of death rates attributable to tobacco. Differences between age groups with respect to tobacco-related mortality were analyzed with respect to differences in terms of development and status of smoking and snus use. The analyses also paid attention to differences between countries regarding tobacco control regulations. Among men in the European Union Member States the lowest level of mortality attributable to tobacco was consistently found in Sweden, while Swedish women showed levels similar to European average. A strong co-variation was found between the mortality advantage and the degree of dominance of snus use in the different age groups of Swedish men. Among Swedish women there are no age groups with dominant use of snus, and similar observations were therefore not possible for women. The above findings support the assumption that the widespread use of snus instead of cigarettes among Swedish men may be a major part of the explanation behind their position with Europe's lowest mortality attributable to tobacco.

The aim was to study the effect of a 5-year diet intervention on 24-year mortality in middle aged men with combined hyperlipidaemia. We studied 104 initially healthy men (in 1972) aged 40-49 years with baseline values of total serum cholesterol >6.45 mmol L-1 and fasting triglycerides >2.55 mmol L-1, within the randomized diet and smoking cessation trial of the Oslo study (n = 1232). The participants were randomized to a 5-year diet intervention or a control group. The diet consisted of a traditional lipid-lowering diet with emphasis on reduction of saturated fat, total caloric intake and body weight. The groups were initially well balanced with regard to traditional risk factors for mortality. Thirty-three subjects died during the 24-year observation period [17 of cardiovascular disease (CVD) and 12 of cancer]. In the diet intervention group, mortality was 51% lower (RR = 0.49, 95% CI 0.22-0.91, P = 0.022) as compared with the control group. This difference remained significant in a Cox regression analysis after adjusting for age and smoking status (RR = 0.47, 95% CI 0.23-0.96, P = 0.038). This study indicates that the investigated 5-year diet intervention significantly reduces late mortality in healthy middle-aged men with combined hyperlipidaemia.

Though still high, the infant mortality rate in Guinea-Bissau has declined. We aimed to identify risk factors including vaccination coverage, for infant mortality in the rural population of Guinea-Bissau and assess whether these risk factors changed from 1992-3 to 2002-3. The Bandim Health Project (BHP) continuously surveys children in rural Guinea-Bissau. We investigated the association between maternal and infant factors (especially DTP and measles coverage) and infant mortality. Hazard ratios (HR) were calculated using Cox regression. We tested for interactions with sex, age groups (defined by current vaccination schedule) and cohort to assess whether the risk factors were the same for boys and girls, in different age groups in 1992-3 and in 2002-3. The infant mortality rate declined from 148/1000 person years (PYRS) in 1992-3 to 124/1000 PYRS in 2002-3 (HR = 0.88;95%CI:0.77-0.99); this decline was significant for girls (0.77;0.64-0.94) but not for boys (0.97;0.82-1.15) (p = 0.10 for interaction). Risk factors did not differ significantly by cohort in either distribution or effect. Mortality decline was most marked among girls aged 9-11 months (0.56;0.37-0.83). There was no significant mortality decline for girls 1.5-8 months of age (0.93;0.68-1.28) (p = 0.05 for interaction). DTP and measles coverage increased from 1992-3 to 2002-3. Risk factors did not change with the decline in mortality. Due to beneficial non-specific effects for girls, the increased coverage of measles vaccination may have contributed to the disproportional decline in mortality by sex and age group.

This work was done to determine the mortality and morbidity rates secondary to asthma in Mexico, for age, gender, state of the country and time. Data were obtained from the Instituto Nacional de Estadística. Geografía e Informática. We calculated morbidity and mortality rates adjusting for age, by a direct method. In the results, there was a reduction in mortality rate in both genders, from 1960 to 1987. Age groups up to 4 years and older than 50 were the mainly affected. From 1960 to the present time, the state with highest mortality is Tlaxcala. The states with highest hospitalization rates were Morelos, Baja California Sur, Nuevo León, Durango and Tamaulipas. In conclusion, mortality rates secondary to asthma in Mexico show a decreasing trend, with a considerable rise in morbidity, especially in the adolescent group.

Determine the relationship between the carcinoembryonic antigen (CEA) value and all-cause mortality in life insurance applicants aged 50 years and over. By use of the Social Security Master Death Index, mortality was examined in 115,590 insurance applicants aged 50 and up for whom blood samples for CEA were submitted to the Clinical Reference Laboratory. Results were stratified by CEA value (<5 ng/mL, 5 to 9.9 ng/mL, 10+ ng/mL), smoking status, and age groups (50-59 years, 60-69 years, and 70 years and up). Relative mortality is increased at CEA values between 5 and 9.9 ng/mL and further increased at 10+ ng/mL for all age groups, with the most dramatic increase at the youngest ages. Excess mortality appears to last at least 3 to 4 years after the elevated result. Five-year all-cause mortality in applicants with CEA values of 10+ ng/mL is 25.2% with a mortality ratio relative to those with a CEA <5 ng/mL of 1156%. This study shows that CEA can detect the risk of early excess mortality in life insurance applicants; CEA levels of 5 ng/mL and over may be of concern. CEA testing beginning at age 50 years for life insurance applicants could capture 4.6% of early mortality if the threshold for further evaluation was set at 10 ng/mL. Only 0.4% of all applicants aged 50 and over have CEA values at or above this threshold.

The relation between tissue AGEs and mortality in end-stage renal disease (ESRD) is documented, but only in hemodialysis (HD) patients. This study aimed to measure and compare tissue AGEs levels in patients receiving either HD or peritoneal dialysis (PD) and to study the effect of these products on all-cause, cardiovascular or sepsis-related mortality. Tissue AGEs were noninvasively assessed in 304 dialysis patients (202 on chronic HD and 102 on continuous ambulatory PD) by measuring skin autofluorescence using a validated Autofluorescence Reader (AGE Reader, DiagnOptics b.v., Groningen, The Netherlands). There was no difference in regard to AGEs levels between the HD (3.6 ± 0.8 AU)- and PD (3.5 ± 0.7 AU, p = 0.2)-treated patients. Diabetic patients had higher AGEs values in the HD group (3.97 ± 0.81 vs. 3.52 ± 0.77, p = 0.002), but not in the PD group (3.68 ± 0.6 vs. 3.45 ± 0.70, p = 0.26). In PD patients, increasing AGEs levels were associated with an elevated risk of all-cause mortality (a 2.09-fold increase for each increment of 1 AU in AGEs values) and sepsis (a 3.44-fold increase for each increment of 1 AU in AGEs values)-related mortality. Performing a similar analysis in diabetic patients, AGEs was associated only with sepsis-related mortality (a 3.08-fold increase for each increment of 1 AU in AGEs values). This is the first study that demonstrates a relationship between tissue AGEs levels and sepsis-related mortality in PD-treated or diabetic ESRD patients. Future studies are necessary to evaluate the non-cardiovascular effects of tissue AGEs in ESRD patients.

The impact of income inequality and national wealth on child and adolescent mortality in low and middle-income countries.

Income inequality and national wealth are strong determinants for health, but few studies have systematically investigated their influence on mortality across the early life-course, particularly outside the high-income world. We performed cross-sectional regression analyses of the relationship between income inequality (national Gini coefficient) and national wealth (Gross Domestic Product (GDP) averaged over previous decade), and all-cause and grouped cause national mortality rate amongst infants, 1-4, 5-9, 10-14, 15-19 and 20-24 year olds in low and middle-income countries (LMIC) in 2012. Gini models were adjusted for GDP. Data were available for 103 (79%) countries. Gini was positively associated with increased all-cause and communicable disease mortality in both sexes across all age groups, after adjusting for national wealth. Gini was only positively associated with increased injury mortality amongst infants and 20-24 year olds, and increased non-communicable disease mortality amongst 20-24 year old females. The strength of these associations tended to increase during adolescence. Increasing GDP was negatively associated with all-cause, communicable and non-communicable disease mortality in males and females across all age groups. GDP was also associated with decreased injury mortality in all age groups except 15-19 year old females, and 15-24 year old males. GDP became a weaker predictor of mortality during adolescence. Policies to reduce income inequality, rather than prioritising economic growth at all costs, may be needed to improve adolescent mortality in low and middle-income countries, a key development priority.

Although income level may play a significant part in mortality among migrants, previous research has not focused on the relationship between income, migration and mortality risk. The aim of this register study was to compare all-cause mortality by income level between different migrant groups and the majority settled population of Finland. A random sample was drawn of 1,058,391 working age people (age range 18-64 years; 50.4% men) living in Finland in 2000 and linked to mortality data from 2001 to 2014. The data were obtained from Statistics Finland. Cox proportional hazards models were used to investigate the association between region of origin and all-cause mortality in low- and high-income groups. The risk for all-cause mortality was significantly lower among migrants than among the settled majority population (hazards ratio (HR) 0.57; 95% confidence interval (CI) 0.53-0.62). After adjustment for age, sex, marital status, employment status and personal income, the risk of mortality was significantly reduced for low-income migrants compared with the settled majority population with a low income level (HR 0.46; 95% CI 0.42-0.50) and for high-income migrants compared with the high-income settled majority (HR 0.81; 95% CI 0.69-0.95). Results comparing individual high-income migrant groups and the settled population were not significant. Low-income migrants from Africa, the Middle East and Asia had the lowest mortality risk of any migrant group studied (HR 0.32; 95% CI 0.27-0.39). Particularly low-income migrants seem to display a survival advantage compared with the corresponding income group in the settled majority population. Downward social mobility, differences in health-related lifestyles and the healthy migrant effect may explain this phenomenon.

The age-specific mortality coefficients and years of life lost as a result of premature mortality are among important medical demographic characteristics of population health. The study analyzed age and sex indicators of mortality of population in the Russian Federation. The number of years of life lost as a result of premature mortality is calculated. The comparison of values of years of life lost in various subjects of the Russian Federation was carried out. The data of Rosstat concerning population size and number of the deceased in year age groups in the Russian Federation and subjects of the Russian Federation in 2012 was used. The indicator was calculated on the basis of technique included into "The global burden of diseases report" (2010). The minimal indicators of mortality of males are noted at the age of 11 years (25.4 per 100 000 of population) and females at the age of 10 years (18.2 per 100 000 of population). The maximal differences in indicators of mortality of males and females are marked in the age group 20-29 years (314.5 of males and 92.3 of females per 100 000 of population). The percentage of deceased prior 70 years consists 63.2% among males and 29.9% among females. The total number of years of life lost in the Russian Federation consisted 36 864 309 and out of them 24 321 992 (65.9%) as a result of death of males and 12 542 317 (34.1%) as a result of death of females. The maximum percentage of years of life lost among males is marked in the age group of 51-60 years (24.61%) and among females in the age group of 71-80 years (22.38%). The indicator of years of life lost per 100 000 of population consisted 25769 for total population, 36 753 for male population and 16 314 for female population. The highest rate of indicator of years of life lost is marked in the Chukchi Autonomous Okrug and the lowest rate in the Republics of the Northern Caucasus and Moscow. However, in all subjects of the Russian Federation indicator of years of life lost is higher than in economically developed countries. The highest rate of indicator of years of life lost in the age group of up to 70 years is marked among males in regions of Siberia and Far East.

Background Cardiovascular disease (CVD) mortality has more than halved in England since the 1980s, but there are few data on small-area trends. We estimated CVD mortality by ward in 5-year intervals between 1982 and 2006, and examined trends in relation to starting mortality, region and community deprivation. Methods We analysed CVD death rates using a Bayesian spatial technique for all 7932 English electoral wards in consecutive 5-year intervals between 1982 and 2006, separately for men and women aged 30–64 years and ≥65 years. Results Age-standardized CVD mortality declined in the majority of wards, but increased in 186 wards for women aged ≥65 years. The decline was larger where starting mortality had been higher. When grouped by deprivation quintile, absolute inequality between most- and least-deprived wards narrowed over time in those aged 30–64 years, but increased in older adults; relative inequalities worsened in all four age–sex groups. Wards with high CVD mortality in 2002–06 fell into two groups: those in and around large metropolitan cities in northern England that started with high mortality in 1982–86 and could not ‘catch up’, despite impressive declines, and those that started with average or low mortality in the 1980s but ‘fell behind’ because of small mortality reductions. Conclusions Improving population health and reducing health inequalities should be treated as related policy and measurement goals. Ongoing analysis of mortality by small area is essential to monitor local effects on health and health inequalities of the public health and healthcare systems. PMID:23129720

The Effect of Serum Sodium on Survival in Patients Treated by Peritoneal Dialysis in the United Kingdom.

PubMed

Al-Chidadi, Asmaa; Nitsch, Dorothea; Davenport, Andrew

♦ BACKGROUND: Studies in hemodialysis patients suggest that hyponatremia is associated with increased mortality. However, results from peritoneal dialysis (PD) patients are discordant. We wished to establish whether there was an association between serum sodium and mortality risk in PD patients. ♦ METHODS: We analyzed 3,108 PD patients enrolled at day 90 of renal replacement therapy (RRT) into the UK Renal Registry (UKRR) data base with available serum sodium measurements (in 3 groups: ≤ 137, 138 - 140, ≥ 141 mmol/L) who were then followed up until death or the censoring date (31 December 2012). Analysis used Cox-regression with adjustment for age, sex, year of starting RRT, primary renal disease, serum albumin, smoking, and comorbidities. ♦ RESULTS: Unadjusted mortality rates were 118.6/1,000 person-years (py), 83.4/1,000 py, and 83.5/1,000 py for the lowest, middle, and highest serum sodium tertiles, respectively. After adjustment for covariates, patients in the lowest serum sodium group had almost 50% increased risk of dying compared with those with the highest serum sodium (hazard ratio [HR] 1.49, confidence interval [CI]:1.28 - 1.74), with a graded association between serum sodium and mortality. The association of serum sodium with mortality varied by age (p interaction < 0.001), and whilst this association attenuated after adjustment for confounding variables in the older age groups (55 - 64, and > 65 years), it remained in the younger age group of 18 - 54 years (HR 2.24 [1.36 - 3.70] in the lowest compared with the highest sodium tertile). ♦ CONCLUSIONS: Lower serum sodium concentrations at the start of RRT in PD patients are associated with increased risk of mortality. Whilst this association may well be due to confounding in the older age groups, the persistent strong association between hyponatremia and mortality in the younger age group after adjustment for the available confounders suggests that prospective studies are required to assess whether active intervention to maintain serum sodium changes outcomes.

To examine in a randomised trial whether a 25% difference in mortality exists between 4.5 months and 3 years of age for children given two standard doses of Edmonston-Zagreb measles vaccines at 4.5 and 9 months of age compared with those given one dose of measles vaccine at 9 months of age (current policy). Randomised controlled trial. The Bandim Health Project, Guinea-Bissau, which maintains a health and demographic surveillance system in an urban area. 6648 children aged 4.5 months of age who had received three doses of diphtheria-tetanus-pertussis vaccine at least four weeks before enrolment. A large proportion of the children (80%) had previously taken part in randomised trials of neonatal vitamin A supplementation. Children were randomised to receive Edmonston-Zagreb measles vaccine at 4.5 and 9 months of age (group A), no vaccine at 4.5 months and Edmonston-Zagreb measles vaccine at 9 months of age (group B), or no vaccine at 4.5 months and Schwarz measles vaccine at 9 months of age (group C). Main outcome measure Mortality rate ratio between 4.5 and 36 months of age for group A compared with groups B and C. Secondary outcomes tested the hypothesis that the beneficial effect was stronger in the 4.5 to 9 months age group, in girls, and in the dry season, but the study was not powered to test whether effects differed significantly between subgroups. In the intention to treat analysis of mortality between 4.5 and 36 months of age the mortality rate ratio of children who received two doses of Edmonston-Zagreb vaccine at 4.5 and 9 months of age compared with those who received a single dose of Edmonston-Zagreb vaccine or Schwarz vaccine at 9 months of age was 0.78 (95% confidence interval 0.59 to 1.05). In the analyses of secondary outcomes, the intention to treat mortality rate ratio was 0.67 (0.38 to 1.19) between 4.5 and 9 months and 0.83 (0.83 to 1.16) between 9 and 36 months of age. The effect on mortality between 4.5 and 36 months of age was significant for girls (intention to treat mortality rate ratio 0.64 (0.42 to 0.98)), although this was not significantly different from the effect in boys (0.95 (0.64 to 1.42)) (interaction test, P=0.18). The effect did not differ between the dry season and the rainy season. As neonatal vitamin A supplementation is not WHO policy, the analyses were done separately for the 3402 children who did not receive neonatal vitamin A. In these children, the two dose Edmonston-Zagreb measles vaccine schedule was associated with a significantly lower mortality between 4.5 and 36 months of age (intention to treat mortality rate ratio 0.59 (0.39 to 0.89)). The effect was again significant for girls but not statistically significant from the effect in boys. When measles cases were censored, the intention to treat mortality rate ratio was 0.65 (0.43 to 0.99). Although the overall effect did not reach statistical significance, the results may indicate that a two dose schedule with Edmonston-Zagreb measles vaccine given at 4.5 and 9 months of age has beneficial non-specific effects on children's survival, particularly for girls and for children who have not received neonatal vitamin A. This should be tested in future studies in different locations. Clinical trials NCT00168558.

This study aims at quantifying the level and changes over time of inequality in age-specific mortality and life expectancy between the 19 Norwegian counties from 1980 to 2014. Data on population and mortality by county was obtained from Statistics Norway for 1980-2014. Life expectancy and age-specific mortality rates (0-4, 5-49 and 50-69 age groups) were estimated by year and county. Geographic inequality was described by the absolute Gini index annually. Life expectancy in Norway has increased from 75.6 to 82.0 years, and the risk of death before the age of 70 has decreased from 26 to 14% from 1980 to 2014. The absolute Gini index decreased over the period 1980 to 2014 from 0.43 to 0.32 for life expectancy, from 0.012 to 0.0057 for the age group 50-69 years, from 0.0038 to 0.0022 for the age group 5-49 years, and from 0.0009 to 0.0006 for the age group 0-4 years. It will take between 2 and 32 years (national average 7 years) until the counties catch up with the life expectancy in the best performing county if their annual rates of increase remain unchanged. Using the absolute Gini index as a metric for monitoring changes in geographic inequality over time may be a valuable tool for informing public health policies. The absolute inequality in mortality and life expectancy between Norwegian counties has decreased from 1980 to 2014.

To examine unintentional drowning mortality by age and body of water across 60 countries, to provide a starting point for further in-depth investigations within individual countries. The latest available three years of mortality data for each country were extracted from WHO Health Statistics and Information Services (updated at 13 November 2013). We calculated mortality rate of unintentional drowning by age group for each country. For countries using International Classification of Disease 10 (ICD-10) detailed 3 or 4 Character List, we further examined the body of water involved. A huge variation in age-standardised mortality rate (deaths per 100 000 population) was noted, from 0.12 in Turkey to 9.19 in Guyana. Of the ten countries with the highest age-standardised mortality rate, six (Belarus, Lithuania, Latvia, Russia, Ukraine and Moldova) were in Eastern Europe and two (Kazakhstan and Kyrgyzstan) were in Central Asia. Some countries (Japan, Finland and Greece) had a relatively low rank in mortality rate among children aged 0-4 years, but had a high rank in mortality rate among older adults. On the contrary, South Africa and Colombia had a relatively high rank among children aged 0-4 years, but had a relatively low rank in mortality rate among older adults. With regard to body of water involved, the proportion involving a bathtub was extremely high in Japan (65%) followed by Canada (11%) and the USA (11%). Of the 13 634 drowning deaths involving bathtubs in Japan between 2009 and 2011, 12 038 (88%) were older adults aged 65 years or above. The percentage involving a swimming pool was high in the USA (18%), Australia (13%), and New Zealand (7%). The proportion involving natural water was high in Finland (93%), Panama (87%), and Lithuania (85%). After considering the completeness of reporting and quality of classifying drowning deaths across countries, we conclude that drowning is a high-priority public health problem in Eastern Europe, Central Asia, Japan (older adults involving bathtubs), and the USA (involving swimming pools).

Knowledge of the epidemiology of injuries in children is essential for the planning, implementation and evaluation of preventive measures but recent epidemiological information on injuries in children both in general and by age-group in Scotland is scarce. This study examines the recent pattern of childhood mortality from injury by age-group in Scotland and considers its implications for prevention. Routine mortality data for the period 2002-2006 were obtained from the General Register Office for Scotland and were analysed in terms of number of deaths, mean annual mortality rates per 100,000 population, leading causes of death, and causes of injury death. Mid-year population estimates were used as the denominator. Chi-square tests were used to determine statistical significance. 186 children aged 0-14 died from an injury in Scotland during 2002-06 (MR 4.3 per 100,000). Injuries were the leading cause of death in 1-14, 5-9 and 10-14 year-olds (causing 25%, 29% and 32% of all deaths respectively). The leading individual causes of injury death (0-14 years) were pedestrian and non-pedestrian road-traffic injuries and assault/homicide but there was variation by age-group. Assault/homicide, fire and suffocation caused most injury deaths in young children; road-traffic injuries in older ones. Collectively, intentional injuries were a bigger threat to the lives of under-15s than any single cause of unintentional injury. The mortality rate from assault/homicide was highest in infants (<1 year) and decreased with increasing age. Children aged 5-9 were significantly less likely to die from an injury than 0-4 or 10-14 year-olds (p < 0.05). Suicide was an important cause of injury mortality in 10-14 year-olds. Injuries continue to be a leading cause of death in childhood in Scotland. Variation in causes of injury death by age-group is important when targeting preventive efforts. In particular, the threats of assault/homicide in infants, fire in 1-4 year-olds, pedestrian injury in 5-14 year-olds, and suicide in 10-14 year-olds need urgent consideration for preventive action.

Cardiogenic shock (CS) is uncommon in patients suffering from acute myocardial infarction (AMI). Long-term outcome and adverse predictors for outcomes in AMI patients with CS receiving percutaneous coronary interventions (PCI) are unclear. A total of 482 AMI patients who received PCI were collected, including 53 CS and 429 non-CS. Predictors for AMI patients with CS including recurrent MI, cardiovascular (CV) mortality, all-cause mortality, and repeated-PCI were analyzed. The CS group had a lower central systolic pressure and central diastolic pressure (both P < 0.001). AMI patients with hypertension history were less prone to develop CS (P < 0.001). Calcium channel blockers and statins were less frequently used by the CS group than the non-CS group (both P < 0.05) after discharge. Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score, CV mortality, and all-cause mortality were higher in the CS group than the non-CS group (all P < 0.005). For patients with CS, stroke history was a predictor of recurrent MI (P = 0.036). CS, age, SYNTAX score, and diabetes were predictors of CV mortality (all P < 0.05). CS, age, SYNTAX score, and stroke history were predictors for all-cause mortality (all P < 0.05). CS, age, and current smoking were predictors for repeated-PCI (all P < 0.05). PMID:28251160

Although cause-of-death analyses are very important to define public health policy priorities and to evaluate health programs, there is very limited knowledge about mortality profiles and trends in Turkey. The aim of this study was to measure the trends in mortality within three broad cause-of-death groups and their distribution by age groups and gender and to describe the changes of leading causes of death between 1980 and 2013 in Turkey. Descriptive study. In the study, data on the number of deaths by year, gender, age and cause was obtained from the Turkish Statistical Institute. The causes of death were classified as group I: communicable, maternal, perinatal, and nutritional conditions; group II: non-communicable diseases (NCDs); and group III: injuries. Unknown or ill-defined causes of death were distributed within group I and group II. The percentage distribution of the cause-of-death groups by gender and age groups between 1980 and 2013 was identified. Age-standardized mortality rates (ASMRs) per 100,000 of broad causes-of-death groups were calculated using European Standard Population 1976 between 1980 and 2008. Changes in mortality rates per hundred were calculated using the formula ([the rate of last year of the period-the rate of the first year of the period]/the rate of the first year of the period). Gender and age-specific data were analyzed using the Joinpoint software to examine trends and significant changes in trends of mortality rates. Crude death rates for group I, group II, and group III were 157.3, 147.2, and 21.4 per 100,000 in 1980 and 35.3, 377.5, and 15.8 in 2008 for males; 161.8, 120.2, and 5.8 in 1980 and 38.6, 318.4, and 6.4 in 2008 for females, respectively. ASMRs for group I, group II, and group III were 146.3, 394.3, and 29.3 per 100,000 in 1980 and 49.7, 723.6, and 18.8 in 2008 for males; 138.0, 291.5, and 7.6 per 100,000 in 1980 and 47.7, 478.8, and 7.2 in 2008 for females, respectively. The mortality rates of group I for almost all age groups particularly below 5 years of age decreased significantly. This study indicates that Turkey is at an advanced stage in the epidemiological transition, with the majority of the causes of death from NCDs. Considering the regional differences, it is necessary to carry out studies on the specific details of epidemiological transition and the social determinants of deaths in Turkey.

This study probes into site-specific cancer mortality inequalities by employment and occupational group among Belgians, adjusted for other indicators of socioeconomic (SE) position. This cohort study is based on record linkage between the Belgian censuses of 1991 and 2001 and register data on emigration and mortality for 01/10/2001 to 31/12/2011. Belgium. The study population contains all Belgians within the economically active age (25-65 years) at the census of 1991. Both absolute and relative measures were calculated. First, age-standardised mortality rates have been calculated, directly standardised to the Belgian population. Second, mortality rate ratios were calculated using Poisson's regression, adjusted for education, housing conditions, attained age, region and migrant background. This study highlights inequalities in site-specific cancer mortality, both related to being employed or not and to the occupational group of the employed population. Unemployed men and women show consistently higher overall and site-specific cancer mortality compared with the employed group. Also within the employed group, inequalities are observed by occupational group. Generally manual workers and service and sales workers have higher site-specific cancer mortality rates compared with white-collar workers and agricultural and fishery workers. These inequalities are manifest for almost all preventable cancer sites, especially those cancer sites related to alcohol and smoking such as cancers of the lung, oesophagus and head and neck. Overall, occupational inequalities were less pronounced among women compared with men. Important SE inequalities in site-specific cancer mortality were observed by employment and occupational group. Ensuring financial security for the unemployed is a key issue in this regard. Future studies could also take a look at other working regimes, for instance temporary employment or part-time employment and their relation to health. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To compare all cause mortality between the north and south of England over four decades. Population wide comparative observational study of mortality. Five northernmost and four southernmost English government office regions. All residents in each year from 1965 to 2008. Death rate ratios of north over south England by age band and sex, and northern excess mortality (percentage of excess deaths in north compared with south, adjusted for age and sex and examined for annual trends, using Poisson regression). During 1965 to 2008 the northern excess mortality remained substantial, at an average of 13.8% (95% confidence interval 13.7% to 13.9%). This geographical inequality was significantly larger for males than for females (14.9%, 14.7% to 15.0% v 12.7%, 12.6% to 12.9%, P<0.001). The inequality decreased significantly but temporarily for both sexes from the early 80s to the late 90s, followed by a steep significant increase from 2000 to 2008. Inequality varied with age, being higher for ages 0-9 years and 40-74 years and lower for ages 10-39 years and over 75 years. Time trends also varied with age. The strongest trend over time by age group was the increase among the 20-34 age group, from no significant northern excess mortality in 1965-95 to 22.2% (18.7% to 26.0%) in 1996-2008. Overall, the north experienced a fifth more premature (<75 years) deaths than the south, which was significant: a pattern that changed only by a slight increase between 1965 and 2008. Inequalities in all cause mortality in the north-south divide were severe and persistent over the four decades from 1965 to 2008. Males were affected more than females, and the variation across age groups was substantial. The increase in this inequality from 2000 to 2008 was notable and occurred despite the public policy emphasis in England over this period on reducing inequalities in health.

Estimates of biological age based on DNA methylation patterns, often referred to as “epigenetic age”, “DNAm age”, have been shown to be robust biomarkers of age in humans. We previously demonstrated that independent of chronological age, epigenetic age assessed in blood predicted all-cause mortality in four human cohorts. Here, we expanded our original observation to 13 different cohorts for a total sample size of 13,089 individuals, including three racial/ethnic groups. In addition, we examined whether incorporating information on blood cell composition into the epigenetic age metrics improves their predictive power for mortality. All considered measures of epigenetic age acceleration were predictive of mortality (p≤8.2×10−9), independent of chronological age, even after adjusting for additional risk factors (p<5.4×10−4), and within the racial/ethnic groups that we examined (non-Hispanic whites, Hispanics, African Americans). Epigenetic age estimates that incorporated information on blood cell composition led to the smallest p-values for time to death (p=7.5×10−43). Overall, this study a) strengthens the evidence that epigenetic age predicts all-cause mortality above and beyond chronological age and traditional risk factors, and b) demonstrates that epigenetic age estimates that incorporate information on blood cell counts lead to highly significant associations with all-cause mortality.

To assess age- and sex-related changes in the mortality from nervous diseases at the population level. Methods of descriptive statistics and analysis of qualitative traits were applied. We analyzed 13580 medical certificates of cause of death from nervous diseases (all classes of ICD-10). The mortality rate varied with age, the main trend of which was the dynamic growth. Age-specific mortality rates for men and women differed from each other: in most ages (20-24, 30-34, 45-49, 50-54, 55-59, 65-69), the likelihood of mortality was higher in men, and at the age of 5-9, 15-19, 60-64, 70 and more years in women. After the standardization of gender differences by age, the mortality risk of nervous illnesses disappeared (146.74 and 144.16 per 100 thousand for men and women, respectively).  There were significant differences in the proportion of nervous diseases of all-cause mortality among the population in the groups stratified by age and sex. It is believed that situational factors is a cause of actual prevailing of gender age- and sex-related mortality risks. Gender features of age-related risk of mortality from nervous diseases are characterized by the multidirectional dynamics of likelihood of mortality and specific weight of nervous diseases among all causes of mortality. The actual gender features of age-related risk of mortality from nervous diseases are generally caused by situational factors (different age structure and unequal level of the general mortality among male and female population) which disappear after standardization.

Although a number of studies on infectious disease trends in China exist, these studies have not distinguished the age, period, and cohort effects simultaneously. Here, we analyze infectious disease mortality trends among urban and rural residents in China and distinguish the age, period, and cohort effects simultaneously. Infectious disease mortality rates (1990-2010) of urban and rural residents (5-84 years old) were obtained from the China Health Statistical Yearbook and analyzed with an age-period-cohort (APC) model based on Intrinsic Estimator (IE). Infectious disease mortality is relatively high at age group 5-9, reaches a minimum in adolescence (age group 10-19), then rises with age, with the growth rate gradually slowing down from approximately age 75. From 1990 to 2010, except for a slight rise among urban residents from 2000 to 2005, the mortality of Chinese residents experienced a substantial decline, though at a slower pace from 2005 to 2010. In contrast to the urban residents, rural residents experienced a rapid decline in mortality during 2000 to 2005. The mortality gap between urban and rural residents substantially narrowed during this period. Overall, later birth cohorts experienced lower infectious disease mortality risk. From the 1906-1910 to the 1941-1945 birth cohorts, the decrease of mortality among urban residents was significantly faster than that of subsequent birth cohorts and rural counterparts. With the rapid aging of the Chinese population, the prevention and control of infectious disease in elderly people will present greater challenges. From 1990 to 2010, the infectious disease mortality of Chinese residents and the urban-rural disparity have experienced substantial declines. However, the re-emergence of previously prevalent diseases and the emergence of new infectious diseases created new challenges. It is necessary to further strengthen screening, immunization, and treatment for the elderly and for older cohorts at high risk.

Mesoamerican nephropathy is an epidemic of chronic kidney disease (CKD) unrelated to traditional causes, mostly observed in sugarcane workers. We analysed CKD mortality in Costa Rica to explore when and where the epidemic emerged, sex and age patterns, and relationship with altitude, climate and sugarcane production. SMRs for CKD deaths (1970-2012) among population aged ≥20 were computed for 7 provinces and 81 counties over 4 time periods. Time trends were assessed with age-standardised mortality rates. We qualitatively examined relations between mortality and data on altitude, climate and sugarcane production. During 1970-2012, age-adjusted mortality rates in the Guanacaste province increased among men from 4.4 to 38.5 per 100,000 vs. 3.6-8.4 in the rest of Costa Rica, and among women from 2.3 to 10.7 per 100,000 vs. 2.6-5.0 in the rest of Costa Rica. A significant moderate excess mortality was observed among men in Guanacaste already in the mid-1970s, steeply increasing thereafter; a similar female excess mortality appeared a decade later, remaining stable. Male age-specific rates were high in Guanacaste for age categories ≥30, and since the late 1990s also for age range 20-29. The male spatiotemporal patterns roughly followed sugarcane expansion in hot, dry lowlands with manual harvesting. Excess CKD mortality occurs primarily in Guanacaste lowlands and was already present 4 decades ago. The increasing rates among Guanacaste men in hot, dry lowland counties with sugarcane are consistent with an occupational component. Stable moderate increases among women, and among men in counties without sugarcane, suggest coexisting environmental risk factors. Published by the BMJ Publishing Group Limited.

2014-01-01

Background Limited data on mortality from malignant lymphatic and hematopoietic neoplasms have been published for Serbia. Methods The study covered population of Serbia during the 1991–2010 period. Mortality trends were assessed using the joinpoint regression analysis. Results Trend for overall death rates from malignant lymphoid and haematopoietic neoplasms significantly decreased: by −2.16% per year from 1991 through 1998, and then significantly increased by +2.20% per year for the 1998–2010 period. The growth during the entire period was on average +0.8% per year (95% CI 0.3 to 1.3). Mortality was higher among males than among females in all age groups. According to the comparability test, mortality trends from malignant lymphoid and haematopoietic neoplasms in men and women were parallel (final selected model failed to reject parallelism, P = 0.232). Among younger Serbian population (0–44 years old) in both sexes: trends significantly declined in males for the entire period, while in females 15–44 years of age mortality rates significantly declined only from 2003 onwards. Mortality trend significantly increased in elderly in both genders (by +1.7% in males and +1.5% in females in the 60–69 age group, and +3.8% in males and +3.6% in females in the 70+ age group). According to the comparability test, mortality trend for Hodgkin's lymphoma differed significantly from mortality trends for all other types of malignant lymphoid and haematopoietic neoplasms (P<0.05). Conclusion Unfavourable mortality trend in Serbia requires targeted intervention for risk factors control, early diagnosis and modern therapy. PMID:25333862

Influenza disease is a vaccine-preventable cause of morbidity and mortality. The Pan American Health Organization (PAHO) region has invested in influenza vaccines, but few estimates of influenza burden exist to justify these investments. We estimated influenza-associated deaths for 35 PAHO countries during 2002-2008. Annually, PAHO countries report registered deaths. We used respiratory and circulatory (R&C) codes from seven countries with distinct influenza seasonality and high-quality mortality data to estimate influenza-associated mortality rates by age group (0-64, 65-74, and ≥ 75 years) with a Serfling regression model or a negative binomial model. We calculated the percent of all R&C deaths attributable to influenza by age group in these countries (etiologic fraction) and applied it to the age-specific mortality in 13 countries with good mortality data but poorly defined seasonality. Lastly, we grouped the remaining 15 countries into WHO mortality strata and applied the age and mortality stratum-specific rate of influenza mortality calculated from the 20 countries. We summed each country's estimate to arrive at an average total annual number and rate of influenza deaths in the Americas. For the 35 PAHO countries, we estimated an annual mean influenza-associated mortality rate of 2·1/100,000 among <65-year olds, 31·9/100 000 among those 65-74 years, and 161·8/100,000 among those ≥ 75 years. We estimated that annually between 40,880 and 160,270 persons (mean, 85,100) die of influenza illness in the PAHO region.

To determine the age and cause groups contributing to absolute and relative socio-economic inequalities in paediatric mortality, hospitalisation and tumour incidence over time. Deaths (n= 9559), hospitalisations (n= 834,932) and incident tumours (n= 4555) were obtained for five age groupings (<1, 1-4, 5-9, 10-14, 15-19 years) and four periods (1990-1993, 1994-1997, 1998-2001, 2002-2005) for Québec, Canada. Age- and cause-specific morbidity and mortality rates for males and females were calculated across socio-economic status decile based on a composite deprivation score for 89 urban communities. Absolute and relative measures of inequality were computed for each age and cause. Mortality and morbidity rates tended to decrease over time, as did absolute and relative socio-economic inequalities for most (but not all) causes and age groups, although precision was low. Socio-economic inequalities persisted in the last period and were greater on the absolute scale for mortality and hospitalisation in early childhood, and on the relative scale for mortality in adolescents. Four causes (respiratory, digestive, infectious, genito-urinary diseases) contributed to the majority of absolute inequality in hospitalisation (males 85%, females 98%). Inequalities were not pronounced for cause-specific mortality and not apparent for tumour incidence. Socio-economic inequalities in Québec tended to narrow for most but not all outcomes. Absolute socio-economic inequalities persisted for children <10 years, and several causes were responsible for the majority of inequality in hospitalisation. Public health policies and prevention programs aiming to reduce socio-economic inequalities in paediatric health should account for trends that differ across age and cause of disease. © 2011 The Authors.

Cooper, Rachel; Wallace, Robert B.; Guralnik, Jack M.

2012-01-01

Abstract Background The relationship between menopausal characteristics and later life mortality is unclear. We tested the hypotheses that women with surgical menopause would have increased all-cause and cardiovascular mortality compared with women with natural menopause, and that women with earlier ages at natural or surgical menopause would have greater all-cause and cardiovascular mortality than women with later ages at menopause. Methods Women who participated in the Iowa cohort of the Established Populations for the Epidemiologic Study of the Elderly (n=1684) reported menopausal characteristics and potential confounding variables at baseline and were followed up for up to 24 years. Participants were aged 65 years or older at baseline and lived in rural areas. We used survival analysis to examine the relationships between menopausal characteristics and all-cause and cardiovascular mortality. Results A total of 1477 women (87.7% of respondents) died during the study interval. Women with an age at natural menopause ≥55 years had increased all-cause and cardiovascular disease mortality compared with women who had natural menopause at younger ages. Type of menopause and age at surgical menopause were not related to mortality. These patterns persisted after adjustment for potential confounding variables. Conclusions Among an older group of women from a rural area of the United States, later age at natural menopause was related to increased all-cause and cardiovascular mortality. Monitoring the cardiovascular health of this group of older women may contribute to improved survival times. PMID:21970557

Synergistic effect of age and body mass index on mortality and morbidity in general surgery.

The elderly population (aged 65 y and older) is expected to be the dominant age group in the United States by 2030. In addition, the prevalence of obesity in the United States is growing exponentially. Obese elderly patients are increasingly undergoing elective or emergent general surgery. There are few, if any, studies highlighting the combined effect of age and body mass index (BMI) on surgical outcomes. We hypothesize that increasing age and BMI synergistically impact morbidity and mortality in general surgery. We collected individual-level, de-identified patient data from the Michigan Surgical Quality Collaborative. Subjects underwent general surgery with general anesthetic, were >18 y, and had a BMI between 19 and 60. Primary and secondary outcomes were 30-d "Any morbidity" and mortality (from wound, respiratory, genitourinary, central nervous system, and cardiac systems), respectively. Preoperative risk variables included diabetes, dialysis, steroid use, cardiac risk, wound classification, American Society of Anesthesiology class, emergent cases, and 13 other variables. We conducted binary logistic regression models for 30-d morbidity and mortality to determine independent effects of age, BMI, interaction between both age and BMI, and a saturated model for all independent variables. We identified 149,853 patients. The average age was 54.6 y, and the average BMI was 30.9. Overall 30-d mortality was 2%, and morbidity was 6.7%. Age was a positive predictor for mortality and morbidity, and BMI was negatively associated with mortality and not significantly associated with morbidity. Age combined with higher BMI was positively associated with morbidity and mortality when the higher age groups were analyzed. Saturated models revealed age and American Society of Anesthesiology class as highest predictors of poor outcomes. Although BMI itself was not a major independent factor predicting 30-d major morbidity or mortality, the morbidly obese, elderly (>50 and 70 y, respectively) subgroup may have an increased morbidity and mortality after general surgery. This information, along with patient-specific factors and their comorbidities, may allow us to better take care of our patients perioperatively and better inform our patients about their risk of surgical procedures.

Advancements in diagnosis and treatment have resulted in better clinical outcomes after stroke; however, the influence of age and gender on recent trends in death during stroke hospitalization has not been specifically investigated. We assessed the impact of age and gender on nationwide patterns of in-hospital mortality after stroke. Data were obtained from all US states that contributed to the Nationwide Inpatient Sample. All patients admitted to hospitals between 1997 and 1998 (n=1 351 293) and 2005 and 2006 (n=1 202 449), with a discharge diagnosis of stroke (identified by the International Classification of Diseases, Ninth Revision procedure codes), were included. Time trends for in-hospital mortality after stroke were evaluated by gender and age group based on 10-year age increments (<55, 55-64, 65-74, 75-84, >84) using multivariable logistic regression. Between 1997 and 2006, in-hospital mortality rates decreased across time in all sub-groups (all P<0·01), except in men >84 years. In unadjusted analysis, men aged >84 years in 1997-1998 had poorer mortality outcomes than similarly aged women (odds ratio 0·93, 95% confidence interval=0·88-0·98). This disparity worsened by 2005-2006 (odds ratio 0·88, 95% confidence interval=0·84-0·93). After adjusting for confounders, compared with similarly aged women, the mortality outcomes among men aged >84 years were poorer in 1997-1998 (odds ratio 0·97, 95% confidence interval=0·92-1·02) and were poorer in 2005-2006 (odds ratio 0·92, 95% confidence interval=0·87-0·96), P=0·04, for gender × time trend. Over the last decade, in-hospital mortality rates after stroke in the United States have declined for every age/gender group, except men aged >84 years. Given the rapidly ageing US population, avenues for boosting in-hospital survival among very elderly men with stroke need to be explored. © 2011 The Authors.

In an investigation of the postmetamorphic survival of a population of 112 Aplysia californica, five animals died before 100 days of age and five after 200 days. The number of survivors among the 102 animals which died between 100 and 220 days declined approximately linearly with age. The median age at death was 155 days. The animals studied were those that died of natural causes within a laboratory population that was established to provide Aplysia for sacrifice in an experimental program. Actuarial separation of the former group from the latter was justified by theoretical consideration. Age-specific mortality rates were calculated from the survival data. Statistical fluctuation arising from the small size of the population was reduced by grouping the data in bins of unequal age duration. The durations were specified such that each bin contained approximately the same number of data points. An algorithm for choosing the number of data bins was based on the requirement that the precision with which the age of a group is determined should equal the precision with which the number of deaths in the groups is known. The Gompertz and power laws of mortality were fitted to the age-specific mortality-rate data with equally good results. The positive values of slope associated with the mortality-rate functions as well as the linear shape of the curve of survival provide actuarial evidence that Aplysia age. Since Aplysia grow linearly without approaching a limiting size, the existence of senescence indicates especially clearly the falsity of Bidder's hypothesis that aging is a by-product of the cessation of growth.

Children with abuse who are admitted to the intensive care unit (ICU) may have high mortality and morbidity and commonly require critical care immediately. It is important to understand the epidemiology and clinical characteristics of these critical cases of child maltreatment.We retrospectively evaluated the data for 355 children with maltreatments admitted to the ICU between 2001 and 2015. Clinical factors were analyzed and compared between the abuse and the neglect groups, including age, gender, season of admission, identifying settings, injury severity score (ISS), etiologies, length of stay (LOS) in the ICU, clinical outcomes, and mortality. In addition, neurologic assessments were conducted with the Pediatric Cerebral Performance Category (PCPC) scale.The most common type of child maltreatments was neglect (n = 259), followed by physical abuse (n = 96). The mean age of the abuse group was less than that of the neglect group (P < .05). Infants accounted for the majority of the abuse group, and the most common etiology of abuse was injury of the central nervous system (CNS). In the neglect group, most were of the preschool age and the most common etiologies of abuse were injury of the CNS and musculoskeletal system (P < .001). The mortality rate in the ICU was 9.86%. The ISS was significantly associated with mortality in both the 2 groups (both P < .05), whereas the LOS in the ICU and injuries of the CNS, musculoskeletal system, and respiratory system were all associated with mortality in the neglect group (all P < .05). The PCPC scale showed poor prognosis in the abuse group as compared to the neglect group (P < .01).In the ICU, children in the abuse group had younger age, higher ISS, and worse neurologic outcome than those in the neglect group. The ISS was a predictor for mortality in the abuse and neglect groups but the LOS in the ICUs, injuries of the CNS, musculoskeletal system, and respiratory system were indicators for mortality in the neglect group. Most importantly, identifying the epidemiological information may provide further strategies to reduce the harm, lower the medical costs, and improve clinical care quality and outcomes in children with abuse.

Background: Little is known about burden of chronic myeloid leukemia (CML) in India. There is a recent interest to observe incidence and mortality because of advent of new diagnostic and treatment policies for CML. Materials and Methods: We extracted data from the oldest population-based cancer registry of Mumbai for 30 years period from 1976−2005 to observe incidence and mortality rates of CML. We classified the data into four age groups 0–14, 15–29, 30–54 and 55–74 to observe incidence rates in the respective age groups. Results: The age specific rates were highest for the age group of 55–74 years. No significant change in trends of CML was observed for 30 years period. However, there was a significant reduction in incidence rate for recent 15-years period (Estimated average annual percentage change=-3.9). No significant reduction in mortality rate was observed till 2005. Conclusion: The study demonstrates that age-specific rates for CML are highest in age group of 55-74 years, although they are lower compared to western populations. Significant reduction in incidence of CML in recent periods might be because of reduced misclassification of leukemias. The data of CML has to be observed for another decade to witness reduction in mortality because of changes in treatment management. PMID:22174498

Patterns of mortality in public and private hospitals of Addis Ababa, Ethiopia

2012-01-01

Background Ethiopia is encountering a growing burden of non-communicable diseases along with infectious diseases, perinatal and nutritional problems that have long been considered major problems of public health importance. This retrospective analysis was carried out to examine the mortality patterns from communicable diseases and non communicable diseases in public and private hospitals of Addis Ababa. Methods Approximately 47,153 deaths were captured over eight years (2002–2010) in forty three public and private hospitals of Addis Ababa, Ethiopia. Data collectors (43 hospital clerks) and coordinators (3 nurses) had been extensively trained on how to review hospital death records. Information obtained included: dates of admission and death, age, sex, address, and principal cause of death. Only the diseases responsible for deaths are taken as the cause of death. Cause of death was coded using International Classification of Diseases (ICD-10) and data were double entered. Diseases were classified into: Group I (communicable diseases, maternal conditions and nutritional deficiencies); Group II (non-communicable causes); and Group III (injuries). Percentages, proportional mortality ratios, 95% confidence intervals (CI) and Adjusted odd ratios (OR) were calculated. Results Overall, 59% of the deaths were attributed to Group I diseases, and 31% to Group II diseases and 12% to injuries. Nearly 56% of the males and 68% of the females deaths were due to five leading causes (conditions arising during perinatal period, HIV/AIDS, tuberculosis, cardiovascular diseases and respiratory infections). Significantly larger proportions of females died from Group I (67%) and Group II diseases (32%) compared with males (where the respective proportions were 52% and 30%). Significantly higher proportion of males (17%) than females (6%) were dying from Group III diseases. Deaths due to Group I diseases decreased while those due to Group II diseases increased with age. Overall Group I diseases and HIV/AIDS, tuberculosis and still birth mortality in particular have showed decreasing trend while Group II and III increasing over time. Double burden in mortality was highly observed in the age groups of 15–64 years. Those aged >45 years were dying more likely with non-communicable diseases compared with children. Children aged below 15 years were 16 times more likely to die from communicable, perinatal and nutritional conditions compared with elders. Mortality variation with age has been identified between public and private hospitals. Conclusions The results of the present study shows that, in addition to the common Group I causes of death, emerging group II diseases are contributing to high proportions of mortality in the public and private hospitals of Addis Ababa, Ethiopia. Thus, priority should be given to the prevention and management of conditions arising during perinatal period such as low birth weight and still birth, HIV/AIDS; tuberculosis, respiratory infections, cardiovascular diseases, malignant neoplasm, chronic respiratory diseases and road traffic accident. The planning of health resources and activities should take into account the double burden in mortality due to Group I and Group II diseases. This calls for strengthening approaches towards the control and prevention of non-communicable diseases such as cardiovascular and malignant neoplasm. PMID:23167315

Favorable mortality profile of naltrexone implants for opiate addiction.

Several reports express concern at the mortality associated with the use of oral naltrexone for opiate dependency. Registry controlled follow-up of patients treated with naltrexone implant and buprenorphine was performed. In the study, 255 naltrexone implant patients were followed for a mean (+/- standard deviation) of 5.22 +/- 1.87 years and 2,518 buprenorphine patients were followed for a mean (+/- standard deviation) of 3.19 +/- 1.61 years, accruing 1,332.22 and 8,030.02 patient-years of follow-up, respectively. The crude mortality rates were 3.00 and 5.35 per 1,000 patient-years, respectively, and the age standardized mortality rate ratio for naltrexone compared to buprenorphine was 0.676 (95% confidence interval = 0.014 to 1.338). Most sex, treatment group, and age comparisons significantly favored the naltrexone implant group. Mortality rates were shown to be comparable to, and intermediate between, published mortality rates of an age-standardized methadone treated cohort and the Australian population. These data suggest that the mortality rate from naltrexone implant is comparable to that of buprenorphine, methadone, and the Australian population.

To estimate excess mortality during heat waves and cold spells, and to identify vulnerable population groups by age and cause of death. Daily mortality in Moscow, Russia from all non-accidental, cardiovascular and respiratory causes between January 2000 and February 2006 was analysed. Mortality and displaced mortality during cold spells and heat waves were estimated using independent samples t tests. Cumulative excess non-accidental mortality during the 2001 heat wave was 33% (95% CI 20% to 46%), or approximately 1200 additional deaths, with short-term displaced mortality contributing about 10% of these. Mortality from coronary heart disease increased by 32% (95% CI 16% to 48%), cerebrovascular mortality by 51% (95% CI 29% to 73%) and respiratory mortality by 80% (95% CI 57% to 101%). In the 75+ age group, corresponding mortality increments were consistently higher except respiratory deaths. An estimated 560 extra deaths were observed during the three heat waves of 2002, when non-accidental mortality increased by 8.5%, 7.8% and 6.1%, respectively. About 40% of these deaths were brought forward by only a few days, bringing net mortality change down to 3.2% (95% CI 0.8% to 5.5%). The cumulative effects of the two cold spells in 2006 on mortality were significant only in the 75+ age group, for which average daily mortality from all non-accidental causes increased by 9.9% (95% CI 8.0% to 12%) and 8.9% (95% CI 6.7% to 11%), resulting in 370 extra deaths; there were also significant increases in coronary disease mortality and cerebrovascular mortality. This study confirms that daily mortality in Moscow increases during heat waves and cold spells. A considerable proportion of excess deaths during heat waves occur a short time earlier than they would otherwise have done. Harvesting, or short-term mortality displacement, may be less significant for longer periods of sustained heat stress.

To assess the influence of age as an independent factor determining the prognosis and outcome of patients with acute myocardial infarction (AMI) treated using primary percutaneous coronary intervention (PCI). A retrospective analysis from a dedicated database. A high-volume interventional cardiology center in the Netherlands. Four thousand nine hundred thirty-three consecutive patients with AMI. Baseline characteristics and clinical outcomes after 30 days and 1 year were compared according to age categorized in three groups: younger than 65, 65 to 74, and 75 and older. A more-detailed analysis was performed with six age groups, from younger than 40 to 80 and older. Of the 4,933 consecutive patients with AMI treated with PCI between 1992 and 2004, 643 were aged 75 and older. Multivariate analysis revealed that patients aged 65 to 75 had a greater risk of 1-year mortality than those younger than 65 (adjusted odds ratio (AOR)=1.57, 95% confidence interval (CI)=1.15-2.16) and that those aged 75 and older had a greater risk of 1-year mortality than those younger than 65 (AOR=3.03, 95% CI=2.14-4.29). In this retrospective analysis, older age was independently associated with greater mortality after PCI for AMI. Patients aged 65 and older had a higher risk of mortality than younger patients, and those aged 75 and older had the highest risk of mortality.

Background Associations between modifiable health risk factors during middle age with disability and mortality in later life are critical to maximizing longevity while preserving function. Positive health effects of maintaining normal weight, routine exercise, and non-smoking are known for the short and intermediate term. We studied the effects of these risk factors into advanced age. Methods A cohort of 2,327 college alumnae ≥60 years was followed annually (1986–2005) by questionnaires addressing health risk factors, history, and Health Assessment Questionnaire disability (HAQ-DI). Mortality data were ascertained from the National Death Index. Low, medium, and high risk groups were created based upon the number (0, 1, ≥2) of health risk factors (overweight, smoking, inactivity) at baseline. Disability and mortality for each group were estimated from unadjusted data and regression analyses. Multivariable survival analyses estimated time to disability or death. Results Medium and high-risk groups had higher disability than the low risk group throughout the study (p<0.001). Low-risk subjects had onset of moderate disability delayed 8.3 years compared with high-risk. Mortality rates were higher in the high risk group (384 versus 247 per 10,000 person-years). Multivariable survival analyses showed the number of risk factors to be associated with cumulative disability and increased mortality. Conclusions Seniors with fewer behavioral risk factors during middle age have lower disability and improved survival. These data document that the associations of lifestyle risk factors upon health continue into the ninth decade. PMID:22269623

Although the overall life expectancy at birth has increased for both blacks and whites and the gap between these populations has narrowed, disparities in life expectancy and the leading causes of death for blacks compared with whites in the United States remain substantial. Understanding how factors that influence these disparities vary across the life span might enhance the targeting of appropriate interventions. Trends during 1999-2015 in mortality rates for the leading causes of death were examined by black and white race and age group. Multiple 2014 and 2015 national data sources were analyzed to compare blacks with whites in selected age groups by sociodemographic characteristics, self-reported health behaviors, health-related quality of life indicators, use of health services, and chronic conditions. During 1999-2015, age-adjusted death rates decreased significantly in both populations, with rates declining more sharply among blacks for most leading causes of death. Thus, the disparity gap in all-cause mortality rates narrowed from 33% in 1999 to 16% in 2015. However, during 2015, blacks still had higher death rates than whites for all-cause mortality in all groups aged <65 years. Compared with whites, blacks in age groups <65 years had higher levels of some self-reported risk factors and chronic diseases and mortality from cardiovascular diseases and cancer, diseases that are most common among persons aged ≥65 years. To continue to reduce the gap in health disparities, these findings suggest an ongoing need for universal and targeted interventions that address the leading causes of deaths among blacks (especially cardiovascular disease and cancer and their risk factors) across the life span and create equal opportunities for health.

Objectives To explore all-cause mortality and the association between symptoms of depression and all-cause mortality in farmers compared with other occupational groups, using a prospective cohort design. Methods We included adult participants with a known occupation from the second wave of the Nord-Trøndelag Health Study (Helseundersøkelsen i Nord-Trøndelag 2 (HUNT2) 1995–1997), Norway. Complete information on emigration and death from all causes was obtained from the National Registries. We used the depression subscale of the Hospital Anxiety and Depression Scale (HADS) to measure symptoms of depression. We compared farmers to 4 other occupational groups. Our baseline study population comprised 32 618 participants. Statistical analyses were performed using the Cox proportional hazards models. Results The estimated mortality risk in farmers was lower than in all other occupations combined, with a sex and age-adjusted HR (0.91, 95% CI 0.82 to 1.00). However, farmers had an 11% increased age-adjusted and sex-adjusted mortality risk compared with the highest ranked socioeconomic group (HR 1.11, 95% CI 0.98 to 1.25). In farmers, symptoms of depression were associated with a 13% increase in sex-adjusted and age-adjusted mortality risk (HR 1.13, 95% CI 0.88 to 1.45). Compared with other occupations this was the lowest HR, also after adjusting for education, marital status, long-lasting limiting somatic illness and lifestyle factors (HR 1.08, 95% CI 0.84 to 1.39). Conclusions Farmers had lower all-cause mortality compared with the other occupational groups combined. Symptoms of depression were associated with an increased mortality risk in farmers, but the risk increase was smaller compared with the other occupational groups. PMID:27188811

While elevated systolic blood pressure (SBP) is related to cardiovascular disease (CVD) mortality, it is unclear if the optimal SBP level may differ by age or the presence of underlying CVD. We investigated the association between SBP categories and CVD mortality among middle-aged and elderly adults with and without CVD history. We used data from 30,692 participants of the population-based Singapore Chinese Health Study who had blood pressures measured using a standard protocol at ages 48-85years between 1994 and 2005. Information on lifestyle factors were collected at recruitment (1993-1998) and during follow-up interviews (1999 and 2004). Mortality was identified via nationwide registry linkage up to 31 December 2014. SBP 120-139mmHg category was associated with lowest risk of CVD mortality in both age-groups of <60 and 60+years, as well as in those with and without underlying coronary heart disease or stroke. Overall, compared to this category, CVD risk was non-significantly increased in lower SBP categories and significantly increased in the higher SBP categories. The risk estimates associated with elevated SBP were higher among those <60years compared to their older counterparts, but less distinct between those with and without underlying CVD. SBP 120-139mmHg was associated with the lowest risk of CVD mortality in middle aged and elderly adults, regardless of underlying CVD. Although risks in both adult groups were similar, there is a greater risk associated with higher SBP among those aged below 60years, highlighting a greater urgency of treatment in this younger group.

Effects of temperature on mortality in Chiang Mai city, Thailand: a time series study

PubMed Central

2012-01-01

Background The association between temperature and mortality has been examined mainly in North America and Europe. However, less evidence is available in developing countries, especially in Thailand. In this study, we examined the relationship between temperature and mortality in Chiang Mai city, Thailand, during 1999–2008. Method A time series model was used to examine the effects of temperature on cause-specific mortality (non-external, cardiopulmonary, cardiovascular, and respiratory) and age-specific non-external mortality (<=64, 65–74, 75–84, and > =85 years), while controlling for relative humidity, air pollution, day of the week, season and long-term trend. We used a distributed lag non-linear model to examine the delayed effects of temperature on mortality up to 21 days. Results We found non-linear effects of temperature on all mortality types and age groups. Both hot and cold temperatures resulted in immediate increase in all mortality types and age groups. Generally, the hot effects on all mortality types and age groups were short-term, while the cold effects lasted longer. The relative risk of non-external mortality associated with cold temperature (19.35°C, 1st percentile of temperature) relative to 24.7°C (25th percentile of temperature) was 1.29 (95% confidence interval (CI): 1.16, 1.44) for lags 0–21. The relative risk of non-external mortality associated with high temperature (31.7°C, 99th percentile of temperature) relative to 28°C (75th percentile of temperature) was 1.11 (95% CI: 1.00, 1.24) for lags 0–21. Conclusion This study indicates that exposure to both hot and cold temperatures were related to increased mortality. Both cold and hot effects occurred immediately but cold effects lasted longer than hot effects. This study provides useful data for policy makers to better prepare local responses to manage the impact of hot and cold temperatures on population health. PMID:22613086

To investigate the association between body-mass index and mortality in Chinese adults T2DM. 11,449 participants of Kailuan Study with T2DM were included in this prospective cohort study. All-cause mortality was calculated using Kaplan-Meier analysis. Cox proportional hazards analysis was used to estimate the association between BMI and mortality. During a mean follow-up period of 7.25±1.42years, 1254 deaths occurred. The number of deaths of the underweight, normal weight, overweight, and obese group was 23, 389, 557, and 285; the corresponding mortality was 25.0%, 13.4%, 10.3%, and 9.4%, respectively. The obese group had the lowest all-cause mortality rate (log-rank chi-square=48.430, P<0.001). After adjusting for age, sex, fasting blood glucose, smoking status, systolic blood pressure, history of hypertension, stroke, cancer and myocardial infarction, compared with the normal weight group, Multivariate Cox proportional hazard regression analysis showed that HR (95% CI) of all-cause mortality in the underweight, overweight, and obese group was 1.497 (0.962, 2.330), 0.833 (0.728, 0.952), and 0.809 (0.690, 0.949). After stratifying for age tertiles, this trend remained. In T2DM patients in north China, the risk for all-cause mortality was lower in the overweight and the obese groups than those in the normal weight and the underweight groups.

Colorectal cancer (CRC) is the second most common cause of cancer death in developed countries among men (after lung cancer) and the third most common among women. This study thus examines the long-term trends of CRC mortality in Taiwan. CRC cases were collective between patients aged 30 years or older and younger than 85 years from the Taiwan death registries during 1971-2010. Standard descriptive techniques such as age-standardized mortality rates (ASMR), aural percent change, and age-period-cohort analyses were used. The increase of percentage change by each age group in men was higher than in women. The ASMR of CRC increased 2-fold for men and almost 1.5-fold for women during the periods 1971-1975 and 2006-2010. For age-period-cohort analysis, the estimated mortality rate increased steadily with age in both sexes, and plateaued at 175.29 per 100,000 people for men and 128.14 per 100,000 for women in the 80- to 84-year-old group. Period effects were weak in both sexes. Cohort effects were strong. Between 30 and 59 years of age, the sex ratio showed that the female CRC mortality rate was higher than that of their male counterparts. Conversely, the mortality risk of CRC in men was higher than that in women when they were between 60 and 84 years old. The current findings showed a consistent increase in mortality from CRC over the years. Changes in the patient sex ratio indicated an important etiological role of sex hormones, especially in women aged 60 years or younger.

Analyses of children and young people mortality continue to be an important component of health monitoring of this population. Such analyses provide the basis to assess the overall trends, the structure of the causes of death over longer periods, and the differences between Poland and other countries. The purpose of the current study is to present the current status and the direction of changes since 2000 with regard to the level and underlying causes of mortality in children and adolescents aged 1-19 years in Poland on the background of statistics for leading European countries. Interactive databases available online: the National Demographic Database provided by the Central Statistical Office and the International WHO-MDB Database were used. Poland, constantly belonging to Eur-B category, was compared with the combined group of 27 leading countries, classified as a very low total mortality group (Eur-A) according to WHO. Linear trends of overall and cause-specific mortality in 2000-2013 were estimated. The causes of death have been presented according to the main classes of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). External and other causes were adopted as the two principal categories. In 2015, 1471 deaths of persons aged 1-19 were recorded in Poland (19.9 per 100 000, 25.4 and 14.2 for boys and girls, respectively). Changes in children and adolescents mortality by age have a non-linear nature (U-shaped), and the lowest level is recorded at the age of 5-9 years. According to 2014 data, 50.2% of deaths of children and adolescents aged 1-19 years occurred due to external causes, including non-intentional and intentional ones. This percentage increased from 18.4% in the 1-4 age group to 68.6% at the age of 15-19 years. Apart from external causes, the dominating causes of death are malignant neoplasms, congenital defects, or nervous system and respiratory system diseases. The ranking of those causes of death changes in successive age groups and over time. When age is considered, a higher proportion of congenital defects and respiratory system diseases was found in mortality younger children and a higher proportion of circulatory system diseases and undefined cases in mortality of adolescents. When trends were studied, a continuing elimination of infectious diseases was observed together with growing impact of rare diseases in all age groups. The excess mortality of Polish population at age 1-19 by comparison to Eur-A countries increased from 21% in 2000 to 56% in 2013, mainly due to unfavourable trends in adolescents. The rate of decline in the mortality of young children (1-4 years) was greater than in Eur-A countries, both in case of external and other causes. In the age group 5-14 years the higher rate of change was sustained only with regard to external causes. Among adolescents and young adults, the distance between Poland and Eur-A countries increased during the studied period. The shape of trend in the 15-24 age group was unfavourable for Poland, mainly with respect to external causes. This observation could be in part explained by increasing suicide trend in Poland since 2008, coexisting with rather constant level in Eur-A countries. The mortality rate among the population aged 1-19 years in Poland is systematically decreasing, but it still exceeds the average level recorded in leading European countries, particularly in relation to adolescents. When assessing the ability to reduce mortality in Poland to the level of Eur-A countries, attention must be paid to the causes considered as avoidable. Further studies ought to focus on the trends and international comparisons only foreshadowed in this study with regard to individual diagnoses, discussing possible preventive measures. Introduction of an ICD-11 classification will enable more accurate coding of causes of death, including a more precise analysis of the burden of rare diseases, which are an increasing challenge to public health in the population at the developmental age.

Mortality from violent causes in the Americas.

This article provides an assessment of 1986 mortality from violent causes in the Americas. Directed at assisting with development of preventive public health measures, it employs data available in the PAHO data base to focus on the under-25 year age group, compare mortality from violent causes with mortality from infectious and parasitic diseases, and evaluate the relative role of motor vehicle traffic accidents, other accidents, suicide, homicide, and deaths from unknown causes in mortality from violent causes. The study uses the classification of causes presented in the International Classification of Diseases, Ninth Revision. The results show that 517,465 deaths from violent causes were registered in 28 countries and political units of the Americas in 1986, mortality from these causes ranging from 19.3 deaths per 100,000 inhabitants in Jamaica to 125 in El Salvador. Examination of available 1980-1986 data from five countries points to steady increases in mortality from violent causes in Brazil and Cuba that began respectively in 1983 and 1984. Assessment of male and female 1986 mortality from these causes in nine countries showed male mortality to be substantially higher, the lowest male:female ratio (in Cuba) being 1.9:1. Among infants, infectious and parasitic disease mortality was greater than mortality from violent causes in most countries. However, from age 1 to the study's 25-year cutoff, mortality from violent causes was found to exceed infectious and parasitic disease mortality in most countries and to play an especially large role in deaths among those 19-24 years old. Data from eight countries suggested that accidents other than motor vehicle traffic accidents were accounting for much of the mortality from violent causes among infants and the 1-4 year age group in 1986, while motor vehicle traffic accidents rivaled other accidents in importance among the older (5-9, 10-14, 15-19, and 19-24) age groups. It appears that the information presented could prove of considerable use in developing policies designed to reduce morbidity and mortality from violent causes (1).

Mortality in developing countries has multiple causes. Some of these causes are linked to climatic conditions that differ over the year. Data on season-specific mortality are sparse. We analysed longitudinal data from a population of approximately 35,000 individuals in Burkina Faso. During the observation period 1993-2001, a total number of 4,098 deaths were recorded. The effect of season on mortality was investigated separately by age group as (i) date of death and (ii) date of birth. For (i), age-specific death rates by month of death were calculated. The relative effect of each month was assessed using the floating relative risk method and modelled continuously. For (ii), age-specific death rates by month of birth were calculated and the mean date of birth among deaths and survivors was compared. Overall mortality was found to be consistently higher during the dry season (November to May). The pattern was seen in all age groups except in infants where a peak was seen around the end of the rainy season. In infants we found a strong association between high mortality and being born during the time period September to February. No effect was seen for the other age groups. The observed excess mortality in young children at or around the end of the rainy season can be explained by the effects of infectious diseases and, in particular, malaria during this time period. In contrast, the excess mortality seen in older children and adults during the early dry season remains largely unexplained although specific infectious diseases such as meningitis and pneumonia are possible main causes. The association between high infant mortality and being born at around the end of the rainy season is probably explained by most of the malaria deaths in areas of high transmission intensity occurring in the second half of infancy.

Raising calves and youngstock is an essential part of beef production. High on-farm mortality (unassisted death and euthanasia) is a consequence of poor animal health and welfare, and is economically unfavourable. The present study aimed to identify the reasons and risk factors for beef calf and youngstock on-farm mortality, using registry data for the years 2013 to 2015. Cox regression models were applied for the data of four age groups: calves up to 30 days (n=21 075), calves 1 to 5 months (n=21 116), youngstock 6 to 19 months (n=22 637) and youngstock ⩾20 months of age (n=9582). We found that dystocia, small birth weight and older parity of the mother increased the mortality hazard in calves up to 30 days of age. A summer birth was a common protective factor against mortality for calves up to 30 days and calves 1 to 5 months of age, compared with birth in other seasons. Among calves 1 to 5 months old, being the offspring of a first-parity cow was associated with significantly higher risk of death compared with calves who were the offspring of third- or higher-parity cows. A high herd-level stillbirth rate was associated with higher mortality hazard. The most commonly reported reasons for calf mortality were digestive disorders and respiratory disease. According to the models of youngstock from 6 months of age, male sex was a risk factor for mortality. Cattle having more than 10% dairy breed experienced a higher mortality risk in the ⩾20 months age group. No significant differences were found across regions, herd size or different breeds in any of the calf or youngstock groups. Metabolic and digestive disorders, as well as traumas and accidents, were the most common causes of mortality in beef youngstock older than 6 months. We can conclude that in young calves, animal-level factors associated with calving had a high impact on mortality. Further, timing calving for the warmer spring months would benefit calf survivability. Further studies including complementary information about farm factors adapted across the whole youngstock period is highly needed to provide sound recommendations in reducing on-farm mortality.

The purpose of this study was to examine US accidental poisoning death rates by demographic and geographic factors from 1979 to 2014, including High Intensity Drug Trafficking Areas. Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 9th revision: E850-E869; ICD 10th revision: X40-X49) from 1979 to 2014 using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 2014 to 1979, overall, by sex, age group, race, and county. Joinpoint regression detected changes in trends and calculated the average annual percentage change (AAPC) as a summary measure of trend. Drug poisoning mortality rates have risen an average of 6% per year since 1979. Increases are occurring in all ages 15+, and in all race-sex groups. HIDTA counties with the highest mortality rates were in Appalachia and New Mexico. Many of the HIDTA border counties had lower rates of mortality. The drug poisoning mortality epidemic is continuing to grow. While HIDTA resources are appropriately targeted at many areas in the US most affected, rates are also rapidly rising in some non-HIDTA areas. Copyright © 2016 Elsevier Inc. All rights reserved.

Sex ratio in multiple sclerosis mortality over 65 years; an age-period-cohort analysis in Norway.

Increasing female: male ratio in multiple sclerosis (MS) has been assigned to cohort effects, with females in more recent birth cohorts possibly being more exposed or vulnerable to environmental risk factors than males. We collected MS mortality data in Norway from 1951 to 2015 from The Norwegian Cause of Death registry. Age-Period-Cohort analysis was conducted using log-linear Poisson models, including sex interaction terms. MS was registered as the underlying, contributing or direct cause in 6060 deaths. MS associated mortality remained stable with a slight preponderance among males until after 1980, and have since increased preferentially among females. Throughout the study period the mean annual increase was 1.25% for females and 0.3% for males (p < 0.0001). Age-period-cohort analysis revealed limited evidence of cohort effects for the gender differences; the best fitting model only included gender-age and gender-period interaction terms. The period effect evened out for males in the last three decades but increased for females, especially among the oldest age-groups. In conclusion, the increased female: male mortality ratio in MS associated mortality is driven mainly by increased mortality among females in the three last decades, particularly in the older age groups. It is best explained by disproportional period effects, providing evidence of time-varying external factors including improved access to diagnosis among females.

Distinct Age and Self-Rated Health Crossover Mortality Effects for African Americans: Evidence from a National Cohort Study

The predictive effects of age and self-rated health (SRH) on all-cause mortality are known to differ across race and ethnic groups. African American adults have higher mortality rates than Whites at younger ages, but this mortality disparity diminishes with advancing age and may “crossover” at about 75 to 80 years of age, when African Americans may show lower mortality rates. This pattern of findings reflects a lower overall association between age and mortality for African Americans than for Whites, and health-related mechanisms are typically cited as the reason for this age-based crossover mortality effect. However, a lower association between poor SRH and mortality has also been found for African Americans than for Whites, and it is not known if the reduced age and SRH associations with mortality for African Americans reflect independent or overlapping mechanisms. This study examined these two mortality predictors simultaneously in a large epidemiological study of 12,181 African Americans and 17,436 Whites. Participants were 45 or more years of age when they enrolled in the national REasons for Geographic and Racial Differences in Stroke (REGARDS) study between 2003 and 2007. Consistent with previous studies, African Americans had poorer SRH than Whites even after adjusting for demographic and health history covariates. Survival analysis models indicated statistically significant and independent race*age, race*SRH, and age*SRH interaction effects on all-cause mortality over an average 9-year follow-up period. Advanced age and poorer SRH were both weaker mortality risk factors for African Americans than for Whites. These two effects were distinct and presumably tapped different causal mechanisms. This calls into question the health-related explanation for the age-based mortality crossover effect and suggests that other mechanisms, including behavioral, social, and cultural factors, should be considered in efforts to better understand the age-based mortality crossover effect and other longevity disparities.

There is a paucity of studies on socioeconomic inequalities in cancer mortality in developing countries. We examined trends in inequalities in cancer mortality by educational attainment in Colombia during a period of epidemiological transition and rapid expansion of health insurance coverage. Population mortality data (1998-2007) were linked to census data to obtain age-standardised cancer mortality rates by educational attainment at ages 25-64 years for stomach, cervical, prostate, lung, colorectal, breast and other cancers. We used Poisson regression to model mortality by educational attainment and estimated the contribution of specific cancers to the slope index of inequality in cancer mortality. We observed large educational inequalities in cancer mortality, particularly for cancer of the cervix (rate ratio (RR) primary vs tertiary groups=5.75, contributing 51% of cancer inequalities), stomach (RR=2.56 for males, contributing 49% of total cancer inequalities and RR=1.98 for females, contributing 14% to total cancer inequalities) and lung (RR=1.64 for males contributing 17% of total cancer inequalities and 1.32 for females contributing 5% to total cancer inequalities). Total cancer mortality rates declined faster among those with higher education, with the exception of mortality from cervical cancer, which declined more rapidly in the lower educational groups. There are large socioeconomic inequalities in preventable cancer mortality in Colombia, which underscore the need for intensifying prevention efforts. Reduction of cervical cancer can be achieved through reducing human papilloma virus infection, early detection and improved access to treatment of preneoplastic lesions. Reinforcing antitobacco measures may be particularly important to curb inequalities in cancer mortality. Published by the BMJ Publishing Group Limited.

Chronic health conditions are commonplace in older populations. The process of aging impacts many of the world's top health concerns. With the average life expectancy continuing to climb, understanding patterns of morbidity in aging populations has become progressively more important. Cancer is an age-related disease, whose risk has been proven to increase with age. Limited information is published about the epidemiology of cancer and the cancer contribution to mortality in the 85+ age group, often referred to as the oldest-old. In this review, we perform a comprehensive assessment of the most recent (2011-2016) literature on cancer prevalence, incidence and mortality in the oldest-old. The data shows cancer prevalence and cancer incidence increases until ages 85-89, after which the rates decrease into 100+ ages. However the number of overall cases has steadily increased over time due to the rise in population. Cancer mortality continues to increase after age 85+. This review presents an overview of plausible associations between comorbidity, genetics and age-related physiological effects in relation to cancer risk and protection. Many of these age-related processes contribute to the lowered risk of cancer in the oldest-old, likewise other certain health conditions may "protect" from cancer in this age group.

To determine the extent to which educational inequalities in relation to mortality widened in Norway during 1960-2000 and which causes of death were the main drivers of this disparity. Nationally representative prospective study. Four cohorts of the Norwegian population aged 45-64 years in 1960, 1970, 1980, and 1990 and followed up for mortality over 10 years. 359 547 deaths and 32 904 589 person years. All cause mortality and deaths due to cancer of lung, trachea, or bronchus; other cancer; cardiovascular diseases; suicide; external causes; chronic lower respiratory tract diseases; or other causes. Absolute and relative indices of inequality were used to present differences in mortality by educational level (basic, secondary, and tertiary). Mortality fell from the 1960s to the 1990s in all educational groups. At the same time the proportion of adults in the basic education group, with the highest mortality, decreased substantially. As mortality dropped more among those with the highest level of education, inequalities widened. Absolute inequalities in mortality denoting deaths among the basic education groups minus deaths among the high education groups doubled in men and increased by a third in women. This is equivalent to an increase in the slope index of inequality of 105% in men and 32% in women. Inequalities on a relative scale widened more, from 1.33 to 2.24 among men (P=0.01) and from 1.52 to 2.19 among women (P=0.05). Among men, absolute inequalities mainly increased as a result of cardiovascular diseases, lung cancer, and chronic lower respiratory tract diseases. Among women this was mainly due to lung cancer and chronic lower respiratory tract diseases. Unlike the situation in men, absolute inequalities in deaths due to cardiovascular causes narrowed among women. Chronic lower respiratory tract diseases contributed more to the disparities in inequalities among women than among men. All educational groups showed a decline in mortality. Nevertheless, and despite the fact that the Norwegian welfare model is based on an egalitarian ideology, educational inequalities in mortality among middle aged people in Norway are substantial and increased during 1960-2000.

Little is known about the interaction between socio-economic status and 'protected characteristics' in Scotland. This study aimed to examine whether differences in mortality were moderated by interactions with social class or deprivation. The practical value was to pinpoint population groups for priority action on health inequality reduction and health improvement rather than a sole focus on the most deprived socioeconomic groups. We used data from the Scottish Longitudinal Study which captures a 5.3 % sample of Scotland and links the censuses of 1991, 2001 and 2011. Hazard ratios for mortality were estimated for those protected characteristics with sufficient deaths using Cox proportional hazards models and through the calculation of European age-standardised mortality rates. Inequality was measured by calculating the Relative Index of Inequality (RII). The Asian population had a polarised distribution across deprivation deciles and was more likely to be in social class I and II. Those reporting disablement were more likely to live in deprived areas, as were those raised Roman Catholic, whilst those raised as Church of Scotland or as 'other Christian' were less likely to. Those aged 35-54 years were the least likely to live in deprived areas and were most likely to be in social class I and II. Males had higher mortality than females, and disabled people had higher mortality than non-disabled people, across all deprivation deciles and social classes. Asian males and females had generally lower mortality hazards than majority ethnic ('White') males and females although the estimates for Asian males and females were imprecise in some social classes and deprivation deciles. Males and females who reported their raised religion as Roman Catholic or reported 'No religion' had generally higher mortality than other groups, although the estimates for 'Other religion' and 'Other Christian' were less precise.Using both the area deprivation and social class distributions for the whole population, relative mortality inequalities were usually greater amongst those who did not report being disabled, Asians and females aged 35-44 years, males by age, and people aged <75 years. The RIIs for the raised religious groups were generally similar or too imprecise to comment on differences. Mortality in Scotland is higher in the majority population, disabled people, males, those reporting being raised as Roman Catholics or with 'no religion' and lower in Asians, females and other religious groups. Relative inequalities in mortality were lower in disabled than nondisabled people, the majority population, females, and greatest in young adults. From the perspective of intersectionality theory, our results clearly demonstrate the importance of representing multiple identities in research on health inequalities.

- To determine the all-cause mortality of life insurance applicants diagnosed with prostate cancer currently or at some time in the past. - Prostate cancer is common and a frequent cause of cancer death. Both the frequency of prostate cancer in men and its propensity for causing premature mortality require insurance company medical directors and underwriters to have a good understanding of prostate cancer-related mortality trends, patterns, and outcomes in the insured population. - Life insurance applicants with reported prostate cancer were extracted from data covering United States residents between November 2007 and November 2014. Information about these applicants was matched to the Social Security Death Master (SSDMF) file for deaths occurring from 2007 to 2011 and to another commercially available death source file (Other Death Source, ODS) for deaths occurring from 2007 to 2014 to determine vital status. Actual to Expected (A/E) mortality ratios were calculated using the Society of Actuaries 2015 Valuation Basic Table (2015VBT), select and ultimate table (age last birthday) and the 2013 US population as expected mortality ratios. All expected bases were not smoker distinct. - The study covered applicants between the ages of 45 and 75 and had approximately 405,000 person-years of exposure. Older aged applicants had a lower mortality ratio than those who were younger. Applicants 45 to 54 had the highest mortality ratios in the first year after diagnosis which steadily decreased in years 6 to 10 with an increase in the mortality ratio for those over 10 years from diagnosis. Relative mortality rate was close to unity for those with localized cancer across all age groups. The mortality ratio was 2 to 4 times greater for those with cancer in 1 positive node, and much greater with 3 positive nodes. For each time-from-diagnosis category, the relative mortality ratios compared to age were highest in the 45-54 age group. The A/E mortality ratios based on the 2015VBT were consistently 3 to 4 times that of the mortality ratios based on the 2013 US population. - The mortality patterns of insurance applicants with prostate cancer were similar to that observed in individuals with prostate cancer in the general population. Applicant age, time to diagnosis and cancer severity were the most significant variables to predict mortality.

Injuries are a neglected cause of child mortality globally and the burden is unequally distributed in resource poor settings. The aim of this study is to explore the share and distribution of child injury mortality across country economic levels and the correlation between country economic level and injuries. All-cause and injury mortality rates per 100,000 were extracted for 187 countries for the 1-4 age group and under 5s from the Global Burden of Disease Study 2010. Countries were grouped into four economic levels. Gross domestic product (GDP) per capita was used to determine correlation with injury mortality. For all regions and country economic levels, the share of injuries in all-cause mortality was greater when considering the 1-4 age group than under 5s, ranging from 36.6% in Organization for Economic Cooperation and Development countries to 10.6% in Sub-Saharan Africa. Except for Sub-Saharan Africa, there is a graded association between country economic level and 1-4 injury mortality across regions, with all low-income countries having the highest rates. Except for the two regions with the highest overall injury mortality rates, there is a significant negative correlation between GDP and injury mortality in Latin America and the Caribbean, Eastern Europe/Central Asia, Asia East/South-East and Pacific and North Africa/ Middle East. Child injury mortality is unevenly distributed across regions and country economic level to the detriment of poorer countries. A significant negative correlation exists between GDP and injury in all regions, exception for the most resource poor where the burden of injuries is highest.

Homicide mortality rates in Canada, 2000-2009: Youth at increased risk.

PubMed

Basham, C Andrew; Snider, Carolyn

2016-10-20

To estimate and compare Canadian homicide mortality rates (HMRs) and trends in HMRs across age groups, with a focus on trends for youth. Data for the period of 2000 to 2009 were collected from Statistics Canada's CANSIM (Canadian Statistical Information Management) Table 102-0540 with the following ICD-10-CA coded external causes of death: X85 to Y09 (assault) and Y87.1 (sequelae of assault). Annual population counts from 2000 to 2009 were obtained from Statistics Canada's CANSIM Table 051-0001. Both death and population counts were organized into five-year age groups. A random effects negative binomial regression analysis was conducted to estimate age group-specific rates, rate ratios, and trends in homicide mortality. There were 9,878 homicide deaths in Canada during the study period. The increase in the overall homicide mortality rate (HMR) of 0.3% per year was not statistically significant (95% CI: -1.1% to +1.8%). Canadians aged 15-19 years and 20-24 years had the highest HMRs during the study period, and experienced statistically significant annual increases in their HMRs of 3% and 4% respectively (p < 0.05). A general, though not statistically significant, decrease in the HMR was observed for all age groups 50+ years. A fixed effects negative binomial regression model showed that the HMR for males was higher than for females over the study period [RRfemale/male = 0.473 (95% CI: 0.361, 0.621)], but no significant difference in sex-specific trends in the HMR was found. An increasing risk of homicide mortality was identified among Canadian youth, ages 15-24, over the 10-year study period. Research that seeks to understand the reasons for the increased homicide risk facing Canada's youth, and public policy responses to reduce this risk, are warranted.

The purpose of this study was to investigate the influences of gender and age on defibrillator lead failure and patient mortality. The specific influences of gender and age on defibrillator lead failure have not previously been investigated. This study analyzed the differences in gender and age in relation to defibrillator lead failure and mortality of patients in the Pacemaker and Implantable Defibrillator Leads Survival Study ("PAIDLESS"). PAIDLESS includes all patients at Winthrop University Hospital who underwent defibrillator lead implantation between February 1, 1996 and December 31, 2011. Male and female patients were compared within each age decile, beginning at 15 years old, to analyze lead failure and patient mortality. Statistical analyses were performed using Wilcoxon rank-sum test, Fisher's exact test, Kaplan-Meier analysis, and multivariable Cox regression models. P<.05 was considered statistically significant. No correction for multiple comparisons was performed for the subgroup analyses. A total of 3802 patients (2812 men and 990 women) were included in the analysis. The mean age was 70 ± 13 years (range, 15-94 years). Kaplan-Meier analysis found that between 45 and 54 years of age, leads implanted in women failed significantly faster than in men (P=.03). Multivariable Cox regression models were built to validate this finding, and they confirmed that male gender was an independent protective factor of lead failure in the 45 to 54 years group (for male gender: HR, 0.37; 95% confidence interval, 0.14-0.96; P=.04). Lead survival time for women in this age group was 13.4 years (standard error, 0.6), while leads implanted in men of this age group survived 14.7 years (standard error, 0.3). Although there were significant differences in lead failure, no differences in mortality between the genders were found for any ages or within each decile. This study is the first to compare defibrillator lead failure and patient mortality in relation to gender and age deciles at a single large implanting center. Within the 45 to 54 years group, leads implanted in women failed faster than in men. Male gender was found to be an independent protective factor in lead survival. This study emphasizes the complex interplay between gender and age with respect to implantable defibrillator lead failure and mortality.

To provide an update on trends in asthma mortality in Brazil for two age groups: 0-4 years and 5-34 years. Data on mortality from asthma, as defined in the International Classification of Diseases, were obtained for the 1980-2014 period from the Mortality Database maintained by the Information Technology Department of the Brazilian Unified Health Care System. To analyze time trends in standardized asthma mortality rates, we conducted an ecological time-series study, using regression models for the 0- to 4-year and 5- to 34-year age groups. There was a linear trend toward a decrease in asthma mortality in both age groups, whereas there was a third-order polynomial fit in the general population. Although asthma mortality showed a consistent, linear decrease in individuals ≤ 34 years of age, the rate of decline was greater in the 0- to 4-year age group. The 5- to 34-year group also showed a linear decline in mortality, and the rate of that decline increased after the year 2004, when treatment with inhaled corticosteroids became more widely available. The linear decrease in asthma mortality found in both age groups contrasts with the nonlinear trend observed in the general population of Brazil. The introduction of inhaled corticosteroid use through public policies to control asthma coincided with a significant decrease in asthma mortality rates in both subsets of individuals over 5 years of age. The causes of this decline in asthma-related mortality in younger age groups continue to constitute a matter of debate. Apresentar uma atualização das tendências da mortalidade da asma no Brasil em duas faixas etárias: 0-4 anos e 5-34 anos. Dados relativos ao período de 1980 a 2014 referentes à mortalidade da asma, conforme se definiu na Classificação Internacional de Doenças, foram extraídos Sistema de Informação sobre Mortalidade do Departamento de Tecnologia da Informação do Sistema Único de Saúde. Para analisar as tendências temporais das taxas padronizadas de mortalidade da asma, realizou-se um estudo ecológico de séries temporais com modelos de regressão para as faixas etárias de 0 a 4 anos e 5 a 34 anos. Houve uma tendência linear de redução da mortalidade da asma em ambas as faixas etárias e uma tendência polinomial de terceira ordem na população geral. Embora a mortalidade da asma tenha apresentado redução linear consistente em indivíduos com idade ≤ 34 anos, a taxa de declínio foi maior na faixa etária de 0 a 4 anos. A faixa etária de 5 a 34 anos também apresentou redução linear da mortalidade, e essa redução tornou-se mais pronunciada após o ano de 2004, quando o tratamento com corticosteroides inalatórios tornou-se mais amplamente disponível. A redução linear da mortalidade da asma em ambas as faixas etárias contrasta com a tendência não linear observada na população geral do Brasil. A introdução do uso de corticosteroides inalatórios por meio de políticas públicas de controle da asma coincidiu com uma diminuição significativa das taxas de mortalidade da asma em ambos os subgrupos de indivíduos com mais de 5 anos de idade. As causas dessa redução da mortalidade da asma em faixas etárias mais jovens ainda são objeto de debate.

Recently, the interest in studying pancreatic cancer mortality has increased due to its high lethality. In this work a detailed analysis of pancreatic cancer mortality in Spanish provinces was performed using recent data. A set of multivariate spatial gender-age-period-cohort models was considered to look for potential candidates to analyze pancreatic cancer mortality rates. The selected model combines features of APC (age-period-cohort) models with disease mapping approaches. To ensure model identifiability sum-to-zero constraints were applied. A fully Bayesian approach based on integrated nested Laplace approximations (INLA) was considered for model fitting and inference. Sensitivity analyses were also conducted. In general, estimated average rates by age, cohort, and period are higher in males than in females. The higher differences according to age between males and females correspond to the age groups [65, 70), [70, 75), and [75, 80). Regarding the cohort, the greatest difference between men and women is observed for those born between the forties and the sixties. From there on, the younger the birth cohort is, the smaller the difference becomes. Some cohort differences are also identified by regions and age-groups. The spatial pattern indicates a North-South gradient of pancreatic cancer mortality in Spain, the provinces in the North being the ones with the highest effects on mortality during the studied period. Finally, the space-time evolution shows that the space pattern has changed little over time. PMID:28199327

We examined the effects of duration of residence and age at immigration on mortality among US-born and foreign-born Hispanics aged 25 and older. We analyzed the National Health Interview Survey-National Death Index linked files from 1997-2009 with mortality follow-up through 2011. We used Cox proportional hazard models to examine the effects of duration of US residence and age at immigration on mortality for US-born and foreign-born Hispanics, controlling for various demographic, socioeconomic and health factors. Age at immigration included 4 age groups: <18, 18-24, 25-34, and 35+ years. Duration of residence was 0-15 and >15 years. We observed a mortality advantage among Hispanic immigrants compared to US-born Hispanics only for those who had come to the US after age 24 regardless of how long they had lived in the US. Hispanics who immigrated as youths (<18) did not differ from US-born Hispanics on mortality despite duration of residence. Findings suggest that age at immigration, rather than duration of residence, drives differences in mortality between Hispanic immigrants and the US-born Hispanic population.

To explore all-cause mortality and the association between symptoms of depression and all-cause mortality in farmers compared with other occupational groups, using a prospective cohort design. We included adult participants with a known occupation from the second wave of the Nord-Trøndelag Health Study (Helseundersøkelsen i Nord-Trøndelag 2 (HUNT2) 1995-1997), Norway. Complete information on emigration and death from all causes was obtained from the National Registries. We used the depression subscale of the Hospital Anxiety and Depression Scale (HADS) to measure symptoms of depression. We compared farmers to 4 other occupational groups. Our baseline study population comprised 32 618 participants. Statistical analyses were performed using the Cox proportional hazards models. The estimated mortality risk in farmers was lower than in all other occupations combined, with a sex and age-adjusted HR (0.91, 95% CI 0.82 to 1.00). However, farmers had an 11% increased age-adjusted and sex-adjusted mortality risk compared with the highest ranked socioeconomic group (HR 1.11, 95% CI 0.98 to 1.25). In farmers, symptoms of depression were associated with a 13% increase in sex-adjusted and age-adjusted mortality risk (HR 1.13, 95% CI 0.88 to 1.45). Compared with other occupations this was the lowest HR, also after adjusting for education, marital status, long-lasting limiting somatic illness and lifestyle factors (HR 1.08, 95% CI 0.84 to 1.39). Farmers had lower all-cause mortality compared with the other occupational groups combined. Symptoms of depression were associated with an increased mortality risk in farmers, but the risk increase was smaller compared with the other occupational groups.

Evaluate the interaction between maternal age and education level in neonatal mortality, as well as investigate the temporal evolution of neonatal mortality in each stratum formed by the combination of these two risk factors. A nonconcurrent cohort study, resulting from a probabilistic relationship between the Mortality Information System and the Live Birth Information System. To investigate the risk of neonatal death we performed a logistic regression, with an odds ratio estimate for the combined variable of maternal education and age, as well as the evaluation of additive and multiplicative interaction. The neonatal mortality rate time series, according to maternal education and age, was estimated by the Joinpoint Regression program. The neonatal mortality rate in the period was 8.09‰ and it was higher in newborns of mothers with low education levels: 12.7‰ (adolescent mothers) and 12.4‰ (mother 35 years old or older). Low level of education, without the age effect, increased the chance of neonatal death by 25% (OR = 1.25, 95%CI 1.14-1.36). The isolated effect of age on neonatal death was higher for adolescent mothers (OR = 1.39, 95%CI 1.33-1.46) than for mothers aged ≥ 35 years (OR = 1.16, 95%CI 1.09-1.23). In the time-trend analysis, no age group of women with low education levels presented a reduction in the neonatal mortality rate for the period, as opposed to women with intermediate or high levels of education, where the reduction was significant, around 4% annually. Two more vulnerable groups - adolescents with low levels of education and older women with low levels of education - were identified in relation to the risk of neonatal death and inequality in reducing the mortality rate.

2008-10-01

The National Center for Health Statistics (NCHS) has produced the 1986-2000 National Health Interview Survey (NHIS) Linked Mortality Files by linking eligible adults in the 1986-2000 NHIS cohorts through probabilistic record linkage to the National Death Index to obtain mortality follow-up through December 31, 2002. The resulting files contain more than 120,000 deaths and an average of 9 years of survival time. To assess how well mortality was ascertained in the linked mortality files, NCHS has conducted a comparison of the mortality experience of the 1986-2000 NHIS cohorts with that of the U.S. population. This report presents the results of this comparative mortality assessment. Methods The survival of each annual NHIS cohort was compared with that of the U.S. population during the same period. Cumulative survival probabilities for each annual NHIS cohort were derived using the Kaplan-Meier product limit method, and corresponding cumulative survival probabilities were computed for the U.S. population using information from annual U.S. life tables. The survival probabilities were calculated at various lengths of follow-up for each age-race-sex group of each NHIS cohort and for the U.S. population. Results As expected, mortality tended to be underestimated in the NHIS cohorts because the sample includes only civilian, noninstitutionalized persons, but this underestimation generally was not statistically significant. Statistically significant differences increased with length of follow-up, occurred more often for white females than for the other race-sex groups, and occurred more often in the oldest age groups. In general, the survival experience of the age-race-sex groups of each NHIS cohort corresponds quite closely to that of the U.S. population, providing support that the ascertainment of mortality through the probabilistic record linkage accurately reflects the mortality experience of the NHIS cohorts.

Dunbar, Nancy M; Yazer, Mark H

Use of universally ABO-compatible group AB plasma for trauma resuscitation can be challenging due to supply limitations. Many centers are now using group A plasma during the initial resuscitation of traumatically injured patients. This study was undertaken to evaluate the impact of this practice on mortality and hospital length of stay (LOS). Seventeen trauma centers using group A plasma in trauma patients of unknown ABO group participated in this study. Eligible patients were group A, B, and AB trauma patients who received at least 1 unit of group A plasma. Data collected included patient sex, age, mechanism of injury, Trauma Injury Severity Score (TRISS) probability of survival, and number of blood products transfused. The main outcome of this study was in-hospital mortality differences between group B and AB patients compared to group A patients. Data on early mortality (≤24 hr) and hospital LOS were also collected. There were 354 B and AB patients and 809 A patients. The two study groups were comparable in terms of age, sex, TRISS probability of survival, and total number of blood products transfused. The use of group A plasma during the initial resuscitation of traumatically injured patients of unknown ABO group was not associated with increased in-hospital mortality, early mortality, or hospital LOS for group B and AB patients compared to group A patients. These results support the practice of issuing thawed group A plasma for the initial resuscitation of trauma patients of unknown ABO group. © 2017 AABB.

Trends in mortality from 1965 to 2008 across the English north-south divide: comparative observational study

Objective To compare all cause mortality between the north and south of England over four decades. Design Population wide comparative observational study of mortality. Setting Five northernmost and four southernmost English government office regions. Population All residents in each year from 1965 to 2008. Main outcome measures Death rate ratios of north over south England by age band and sex, and northern excess mortality (percentage of excess deaths in north compared with south, adjusted for age and sex and examined for annual trends, using Poisson regression). Results During 1965 to 2008 the northern excess mortality remained substantial, at an average of 13.8% (95% confidence interval 13.7% to 13.9%). This geographical inequality was significantly larger for males than for females (14.9%, 14.7% to 15.0% v 12.7%, 12.6% to 12.9%, P<0.001). The inequality decreased significantly but temporarily for both sexes from the early 80s to the late 90s, followed by a steep significant increase from 2000 to 2008. Inequality varied with age, being higher for ages 0-9 years and 40-74 years and lower for ages 10-39 years and over 75 years. Time trends also varied with age. The strongest trend over time by age group was the increase among the 20-34 age group, from no significant northern excess mortality in 1965-95 to 22.2% (18.7% to 26.0%) in 1996-2008. Overall, the north experienced a fifth more premature (<75 years) deaths than the south, which was significant: a pattern that changed only by a slight increase between 1965 and 2008. Conclusion Inequalities in all cause mortality in the north-south divide were severe and persistent over the four decades from 1965 to 2008. Males were affected more than females, and the variation across age groups was substantial. The increase in this inequality from 2000 to 2008 was notable and occurred despite the public policy emphasis in England over this period on reducing inequalities in health. PMID:21325004

Modelling small-area inequality in premature mortality using years of life lost rates

NASA Astrophysics Data System (ADS)

Congdon, Peter

2013-04-01

Analysis of premature mortality variations via standardized expected years of life lost (SEYLL) measures raises questions about suitable modelling for mortality data, especially when developing SEYLL profiles for areas with small populations. Existing fixed effects estimation methods take no account of correlations in mortality levels over ages, causes, socio-ethnic groups or areas. They also do not specify an underlying data generating process, or a likelihood model that can include trends or correlations, and are likely to produce unstable estimates for small-areas. An alternative strategy involves a fully specified data generation process, and a random effects model which "borrows strength" to produce stable SEYLL estimates, allowing for correlations between ages, areas and socio-ethnic groups. The resulting modelling strategy is applied to gender-specific differences in SEYLL rates in small-areas in NE London, and to cause-specific mortality for leading causes of premature mortality in these areas.

The mortality burden of the 2009 A/H1N1 pandemic remains unclear in many countries due to delays in reporting of death statistics. We estimate the age- and cause-specific excess mortality impact of the pandemic in France, relative to that of other countries and past epidemic and pandemic seasons. We applied Serfling and Poisson excess mortality approaches to model weekly age- and cause-specific mortality rates from June 1969 through May 2010 in France. Indicators of influenza activity, time trends, and seasonal terms were included in the models. We also reviewed the literature for country-specific estimates of 2009 pandemic excess mortality rates to characterize geographical differences in the burden of this pandemic. The 2009 A/H1N1 pandemic was associated with 1.0 (95% Confidence Intervals (CI) 0.2-1.9) excess respiratory deaths per 100,000 population in France, compared to rates per 100,000 of 44 (95% CI 43-45) for the A/H3N2 pandemic and 2.9 (95% CI 2.3-3.7) for average inter-pandemic seasons. The 2009 A/H1N1 pandemic had a 10.6-fold higher impact than inter-pandemic seasons in people aged 5-24 years and 3.8-fold lower impact among people over 65 years. The 2009 pandemic in France had low mortality impact in most age groups, relative to past influenza seasons, except in school-age children and young adults. The historical A/H3N2 pandemic was associated with much larger mortality impact than the 2009 pandemic, across all age groups and outcomes. Our 2009 pandemic excess mortality estimates for France fall within the range of previous estimates for high-income regions. Based on the analysis of several mortality outcomes and comparison with laboratory-confirmed 2009/H1N1 deaths, we conclude that cardio-respiratory and all-cause mortality lack precision to accurately measure the impact of this pandemic in high-income settings and that use of more specific mortality outcomes is important to obtain reliable age-specific estimates.

Frailty and the metabolic syndrome are each associated with poor outcomes, but in very old people (90+ years) only frailty was associated with an increased mortality risk. We investigated the relationship between frailty, metabolic syndrome, and mortality risk, in younger (20-65 years) and older (65+ years) people. This is a secondary analysis of the US National Health and Nutrition Examination Survey (NHANES) datasets for 2003-2004 and 2005-2006, linked with mortality data up to 2011. The metabolic syndrome was defined using the International Diabetes Federation criteria. Frailty was operationalized using a 41-item frailty index (FI). Compared to the younger group (n = 6403), older adults (n = 2152) had both a higher FI (0.10 ± 0.00 vs. 0.22 ± 0.00, p < 0.001) and a greater prevalence of the metabolic syndrome (24.1 vs. 45.5%, p < 0.001). The metabolic syndrome and FI were correlated in younger people (r = 0.25, p < 0.001) but not in older people (r = 0.08, p < 0.1). In bivariate analyses, the FI predicted mortality risk in both age groups whereas the metabolic syndrome did so only in the younger group. In Cox models, adjusted for age, sex, race, education, and each other, the FI was associated with increased mortality risk at both ages (younger HR 1.05 (1.04-1.06); older HR 1.04 (1.03-1.04) whereas the metabolic syndrome did not contribute to mortality risk. The FI better predicted mortality than did the metabolic syndrome, regardless of age.

This study examined associations between BMI and mortality in individuals with normoglycemia, impaired fasting glucose (IFG), newly diagnosed diabetes, and prevalent diabetes and identified BMI ranges associated with the lowest mortality in each group. A total of 12,815,006 adults were prospectively monitored until 2013. Diabetes status was defined as follows: normoglycemia (fasting glucose <100 mg/dL), IFG (100-125 mg/dL), newly diagnosed diabetes (≥126 mg/dL), and prevalent diabetes (self-reported). BMI (kg/m 2 ) was measured. Cox proportional hazards model hazard ratios were calculated after adjusting for confounders. During a mean follow-up period of 10.5 years, 454,546 men and 239,877 women died. U-shaped associations were observed regardless of diabetes status, sex, age, and smoking history. Optimal BMI (kg/m 2 ) for the lowest mortality by group was 23.5-27.9 (normoglycemia), 25-27.9 (IFG), 25-29.4 (newly diagnosed diabetes), and 26.5-29.4 (prevalent diabetes). Higher optimal BMI by worsening diabetes status was more prominent in younger ages, especially in women. The relationship between worsening diabetes status and higher mortality was stronger with lower BMI, especially at younger ages. Given the same BMI, people with prevalent diabetes had higher mortality compared with those with newly diagnosed diabetes, and this was more striking in women than men. U-curve relationships existed regardless of diabetes status. Optimal BMI for lowest mortality became gradually higher with worsening diabetes for each sex and each age-group. © 2017 by the American Diabetes Association.

Although nearly 112 million residents of the United States belong to a non-white ethnic group, the literature about differences in health indicators across ethnic groups is limited almost exclusively to Hispanics. Features of the social experience of many ethnic groups including immigration, discrimination, and acculturation may plausibly influence mortality risk. We explored life expectancy and age-adjusted mortality risk of Arab-Americans (AAs), relative to non-Arab and non-Hispanic Whites in Michigan, the state with the largest per capita population of AAs in the US. Data were collected about all deaths to AAs and non-Arab and non-Hispanic Whites in Michigan between 1990 and 2007, and year 2000 census data were collected for population denominators. We calculated life expectancy, age-adjusted all-cause, cause-specific, and age-specific mortality rates stratified by ethnicity and gender among AAs and non-Arab and non-Hispanic Whites. Among AAs, life expectancies among men and women were 2.0 and 1.4 years lower than among non-Arab and non-Hispanic White men and women, respectively. AA men had higher mortality than non-Arab and non-Hispanic White men due to infectious diseases, chronic diseases, and homicide. AA women had higher mortality than non-Arab and non-Hispanic White women due to chronic diseases. Despite better education and higher income, AAs have higher age-adjusted mortality risk than non-Arab and non-Hispanic Whites, particularly due to chronic diseases. Features specific to AA culture may explain some of these findings. © 2011 El-Sayed et al.

The success of antiretroviral therapy has led to an increase in the number of older people living with human immunodeficiency virus worldwide. This study analyzed the epidemiological patterns and time trends of acquired immunodeficiency syndrome (AIDS) related mortality in people aged 60 and older in Brazil from 2000 to 2011. Secondary mortality data from the Brazilian Mortality Information System was used to perform a nationwide population-based study, which included all AIDS-related deaths among people aged 60 years and older in Brazil from 2000 to 2011. Crude and age-adjusted mortality rates (per 100,000 inhabitants) were calculated by sex, age group and place of residence. Trends over time were assessed using joinpoint regression analysis. In the 12-year study period, 12,491,280 deaths were recorded in Brazil, of which 144,175 were AIDS-related deaths. A total of 8194 AIDS-related deaths was identified in people aged 60 years and older (0.12% of all deaths and 5.7% of AIDS-related deaths). The overall age-adjusted mortality rate for the period was 4.30 deaths/100,000 inhabitants (95% confidence interval: 3.99-4.64). Males (6.45 deaths/100,000 inhabitants), aged 60-64 years (6.63 deaths/100,000 inhabitants) and residing in the South region (5.94 deaths/100,000 inhabitants) had the highest mortality rates. We observed a significant increase in mortality at the national level and in all the Brazilian regions, with a sharper increase in the most socioeconomically disadvantaged regions of the country, such as the North and Northeast. The findings show that AIDS in older people is an increasing public health problem in Brazil, and reinforce the need to establish public policies for the prevention, early diagnosis and appropriate clinical treatment of this age group.

Low serum bicarbonate associates with mortality in CKD. This study investigated the associations of bicarbonate and acid-base status with mortality in healthy older individuals. We analyzed data from the Health, Aging, and Body Composition Study, a prospective study of well functioning black and white adults ages 70-79 years old from 1997. Participants with arterialized venous blood gas measurements (n=2287) were grouped into <23.0 mEq/L (low), 23.0-27.9 mEq/L (reference group), and ≥28.0 mEq/L (high) bicarbonate categories and according to acid-base status. Survival data were collected through February of 2014. Mortality hazard ratios (HRs; 95% confidence intervals [95% CIs]) in the low and high bicarbonate groups compared with the reference group were determined using Cox models adjusted for demographics, eGFR, albuminuria, chronic obstructive pulmonary disease, smoking, and systemic pH. Similarly adjusted Cox models were performed according to acid-base status. The mean age was 76 years, 51% were women, and 38% were black. Mean pH was 7.41, mean bicarbonate was 25.1 mEq/L, 11% had low bicarbonate, and 10% had high bicarbonate. Mean eGFR was 82.1 ml/min per 1.73 m(2), and 12% had CKD. Over a mean follow-up of 10.3 years, 1326 (58%) participants died. Compared with the reference group, the mortality HRs were 1.24 (95% CI, 1.02 to 1.49) in the low bicarbonate and 1.03 (95% CI, 0.84 to 1.26) in the high bicarbonate categories. Compared with the normal acid-base group, the mortality HRs were 1.17 (95% CI, 0.94 to 1.47) for metabolic acidosis, 1.21 (95% CI, 1.01 to 1.46) for respiratory alkalosis, and 1.35 (95% CI, 1.08 to 1.69) for metabolic alkalosis categories. Respiratory acidosis did not associate with mortality. In generally healthy older individuals, low serum bicarbonate associated with higher mortality independent of systemic pH and potential confounders. This association seemed to be present regardless of whether the cause of low bicarbonate was metabolic acidosis or respiratory alkalosis. Metabolic alkalosis also associated with higher mortality.

Background and objectives Low serum bicarbonate associates with mortality in CKD. This study investigated the associations of bicarbonate and acid-base status with mortality in healthy older individuals. Design, setting, participants, & measurements We analyzed data from the Health, Aging, and Body Composition Study, a prospective study of well functioning black and white adults ages 70–79 years old from 1997. Participants with arterialized venous blood gas measurements (n=2287) were grouped into <23.0 mEq/L (low), 23.0–27.9 mEq/L (reference group), and ≥28.0 mEq/L (high) bicarbonate categories and according to acid-base status. Survival data were collected through February of 2014. Mortality hazard ratios (HRs; 95% confidence intervals [95% CIs]) in the low and high bicarbonate groups compared with the reference group were determined using Cox models adjusted for demographics, eGFR, albuminuria, chronic obstructive pulmonary disease, smoking, and systemic pH. Similarly adjusted Cox models were performed according to acid-base status. Results The mean age was 76 years, 51% were women, and 38% were black. Mean pH was 7.41, mean bicarbonate was 25.1 mEq/L, 11% had low bicarbonate, and 10% had high bicarbonate. Mean eGFR was 82.1 ml/min per 1.73 m2, and 12% had CKD. Over a mean follow-up of 10.3 years, 1326 (58%) participants died. Compared with the reference group, the mortality HRs were 1.24 (95% CI, 1.02 to 1.49) in the low bicarbonate and 1.03 (95% CI, 0.84 to 1.26) in the high bicarbonate categories. Compared with the normal acid-base group, the mortality HRs were 1.17 (95% CI, 0.94 to 1.47) for metabolic acidosis, 1.21 (95% CI, 1.01 to 1.46) for respiratory alkalosis, and 1.35 (95% CI, 1.08 to 1.69) for metabolic alkalosis categories. Respiratory acidosis did not associate with mortality. Conclusions In generally healthy older individuals, low serum bicarbonate associated with higher mortality independent of systemic pH and potential confounders. This association seemed to be present regardless of whether the cause of low bicarbonate was metabolic acidosis or respiratory alkalosis. Metabolic alkalosis also associated with higher mortality.

Religion frequently indicates membership of socio-ethnic groups with distinct health behaviours and mortality risk. Determining the extent to which interactions between groups contribute to variation in mortality is often challenging. We compared socio-economic status (SES) and mortality rates of Protestants and Catholics in Scotland and Northern Ireland, regions in which interactions between groups are profoundly different. Crucially, strong equality legislation has been in place for much longer and Catholics form a larger minority in Northern Ireland. Drawing linked Census returns and mortality records of 404,703 people from the Scottish and Northern Ireland Longitudinal Studies, we used Poisson regression to compare religious groups, estimating mortality rates and incidence rate ratios. We fitted age-adjusted and fully adjusted (for education, housing tenure, car access and social class) models. Catholics had lower SES than Protestants in both countries; the differential was larger in Scotland for education, housing tenure and car access but not social class. In Scotland, Catholics had increased age-adjusted mortality risk relative to Protestants but variation among groups was attenuated following adjustment for SES. Those reporting no religious affiliation were at similar mortality risk to Protestants. In Northern Ireland, there was no mortality differential between Catholics and Protestants either before or after adjustment. Men reporting no religious affiliation were at increased mortality risk but this differential was not evident among women. In Scotland, Catholics remained at greater socio-economic disadvantage relative to Protestants than in Northern Ireland and were also at a mortality disadvantage. This may be due to a lack of explicit equality legislation that has decreased inequality by religion in Northern Ireland during recent decades. Copyright © 2017 Elsevier Ltd. All rights reserved.

The role of atrial fibrillation (AF) in older patients with heart failure (HF) is controversial because many variables seem to influence their outcome. We investigated the predictivity of AF in 3 age groups of outpatients with HF. We analyzed 8,178 outpatients enrolled in the Italian Network on Congestive Heart Failure Registry with HF diagnosed according to the European Society of Cardiology criteria. A trained cardiologist established the diagnosis of AF and HF at the entry visit at each center. We stratified the population into 3 age groups, as follows: group A, < or =65 years; group B, 66-75 years, and group C, >75 years. Group A was composed of 4,261 patients, 683 with AF (16.0%); in group B there were 2,651 patients, 638 with AF (24.1%), and group C was composed of 1,266 patients, 412 with AF (32.5%). The 1-year mortality rate was higher in AF patients in all groups. In a multivariate model, AF remained an independent risk factor for death in groups A and B, but not in group C [group A: hazard ratio (HR) 1.42, 95% confidence interval (CI) 1.10-1.81; group B: HR 1.29, 95% CI 1.00-1.67; group C: HR 1.05, 95% CI 0.78-1.43]. The prevalence of AF increased with age and was associated with a higher mortality rate. However, AF independently predicted all-cause mortality only in patients aged < or =75 years.

We aimed to examine the effect of preinjury antithrombotic medication on clinical and radiologic neuroworsening in traumatic brain injury (TBI) and study the effect on outcome. A total of 184 consecutive patients ≥50 years old with moderate and severe TBI admitted to a level 1 trauma center were included. Neuroworsening was assessed clinically by using the Glasgow Coma Scale (GCS) score and radiologically by using the Rotterdam CT score on repeated time points. Functional outcome was assessed with the Glasgow Outcome Scale Extended 6 months after injury. The platelet inhibitor group (mean age, 77.3 years; n = 43) and the warfarin group (mean age, 73.2 years; n = 20) were significantly older than the nonuser group (mean age, 63.7 years; n = 121; P ≤ 0.001). In the platelet inhibitor group 74% and in the warfarin group, 85% were injured by falls. Platelet inhibitors were not significantly associated with clinical or radiologic neuroworsening (P = 0.37-1.00), whereas warfarin increased the frequency of worsening in GCS score (P = 0.001-0.028) and Rotterdam CT score (P = 0.004). In-hospital mortality was higher in the platelet inhibitor group (28%; P = 0.030) and the warfarin group (50%; P < 0.001) compared with the nonuser group (13%). Platelet inhibitors did not predict mortality or worse outcome after adjustment for age, preinjury disability, GCS score, and Rotterdam CT score, whereas warfarin predicted both mortality and worse outcome. In this study of patients with moderate and severe TBI, preinjury platelet inhibitors did not cause neuroworsening or predict higher mortality or worse outcome. In contrast, preinjury warfarin caused neuroworsening and was an independent risk factor for mortality and worse outcome at 6 months. Hence, fall prevention and liberal use of computed tomography examinations is important in this patient group. Copyright © 2018 The Author(s). Published by Elsevier Inc. All rights reserved.

Pneumonia is now the second leading cause of death for children aged <5 years worldwide. However, analyses of the long-term evolution of under-5 mortality from pneumonia are still scarce in the literature. We aimed to explore long-term trends of under-5 mortality from pneumonia in 56 countries from 1960 to 2012. Data on under-5 mortality from pneumonia were extracted from the World Health Organization mortality database. Long-term trends were assessed for 56 countries and for 4 national income transition groups. We also used joinpoint regression analysis to detect distinct period segments of long-term trends and estimate the annual percent of changes of each period segment. The average mortality rate from pneumonia for children aged 0-4 years in 56 countries declined from 163.0 per 100000 children (95% confidence interval [CI], 119.4 to 212.8) in 1960 to 9.9 per 100000 children (95% CI, 6.4 to 13.4) in 2012, with an average annual percent of change of -5.6% (95% CI, -7.2% to -3.9%). The temporal trends of childhood mortality were different between national income transition groups. Our findings suggest a striking overall downward trend in under-5 mortality from pneumonia between 1960 and 2012. However, the rate and absolute terms of decline differ by national income transition group. These variable patterns between national income transition groups may inform further intervention setting and priority setting. © The Author 2017.

Overweight and mortality in Mexican Americans.

The Geriatric Research Center (GRC) table of desirable weights is based on the mortality experience of holders of 4.2 million policies issued by 25 life insurance companies in the USA and Canada. The GRC table defines optimum weight-for-height as the weight range which is associated with below average mortality for a given age and height group. People who fall outside this range, i.e. overweight or underweight, experience above average mortality for their age and height group. We classified 3176 Mexican Americans and 1841 non-Hispanic whites who participated in the San Antonio Heart Study according to the GRC table and found that Mexican Americans were less likely than non-Hispanic whites to be underweight and more likely to be overweight. The two effects did not offset one another, however, and fewer Mexican Americans were found to be in the 'just right' range. If the mortality experience of the population which generated the GRC table (largely non-Hispanic) applied to Mexican Americans, these results imply that Mexican Americans should have higher mortality rates than non-Hispanic whites. Vital statistics data from the state of Texas for the years 1979-81, however, fail to corroborate this prediction. Beyond age 45 years, an age range in which obesity and obesity-related disorders would be expected to exert an important influence on mortality, age-specific and age-adjusted all cause mortality was at last as good if not better in Mexican Americans than in non-Hispanic whites. These results could not be explained by ethnic differences in body fat distribution, since fat was less favorably distributed in Mexican Americans.(ABSTRACT TRUNCATED AT 250 WORDS)

Identify the factors associated with the age-standardised breast cancer mortality rate in the municipalities of State of São Paulo (SSP), Brazil, in the period from 2006 to 2012. Ecological study of the breast cancer mortality rate standardised by age, as the dependent variable, having each of the 645 municipalities in the SSP as the unit of analysis. The female resident population aged 15 years or older, by age group and municipality, in 2009 (mid-term), obtained from public dataset (Informatics Department of the Unified Health System). Women 15 years or older who died of breast cancer in the SSP were selected for the calculation of the breast cancer mortality rate, according to the municipality and age group, from 2006 to 2012. Mortality rates for each municipality calculated by the direct standardisation method, using the age structure of the population of SSP in 2009 as the standard. In the final linear regression model, breast cancer mortality, in the municipal level, was directly associated with rates of nulliparity (p<0.0001), mammography (p<0.0001) and private healthcare (p=0.006). The findings that mammography ratio was associated, in the municipal level, with increased mortality add to the evidence of a probable overestimation of benefits and underestimation of risks associated with this form of screening. The same paradoxical trend of increased mortality with screening was found in recent individual-level studies, indicating the need to expand informed choice for patients, primary prevention actions and individualised screening. Additional studies should be conducted to explore if there is a causality link in this association. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The literature on the association between apolipoprotein E (ApoE) and mortality across ethnic and age groups has been inconsistent. No studies have looked at this association in developing countries. We used data from the Indianapolis-Ibadan Dementia study to examine this association between APOE and mortality in 354 African-Americans from Indianapolis and 968 Yoruba from Ibadan, Nigeria. Participants were followed up to 9.5 years for Indianapolis and 8.7 years for Ibadan. Subjects from both sites were divided into 2 groups based upon age at baseline. A Cox proportional hazards regression model adjusting for age at baseline, education, hypertension, smoking history and gender in addition to time-dependent covariates of cancer, diabetes, heart disease, stroke, and dementia was fit for each cohort and age group. Having ApoE epsilon4 alleles significantly increased mortality risk in Indianapolis subjects under age 75 (hazard ratio: 2.00; 95% CI: 1.19-3.35; p = 0.0089). No association was found in Indianapolis subjects 75 and older (hazard ratio: 0.71; 95% CI: 0.45-1.10; p = 0.1238), Ibadan subjects under 75 (hazard ratio: 1.04; 95% CI: 0.78 to 1.40; p = 0.7782), or Ibadan subjects over 75 (hazard ratio: 1.21; 95% CI: 0.83 to 1.75; p = 0.3274).

To report trends in mortality from suicide in Colombia from 1985 to 2002 by sex, age group, and method, and determine the number of Years of Potential Life Lost (YPLL) to suicide during this period. Age- and sex-specific and age-adjusted crude mortality rates were calculated based on mortality and population information available from the official database of the Department of National Statistics Administration, Colombia. YPLL were estimated and adjusted for societal impact, age, and poor quality of mortality records. The results were tabulated according to codes X600-X849 and Y870 from the International Statistical Classification of Disease and Related Health Problems, 10th revision (ICD-10), and codes E950-E959 from the 9th revision (ICD-9). Suicide rates have been climbing in Colombia since 1998, particularly among young adults and males. The highest rates among males were in the age groups 20-29 years of age and over 70 years of age, and rates increased over time. Among females, the highest rates were recorded for the group 10-19 years of age. The YPLL rose in proportion with the increase in suicides, from 0.81% in 1981 to 2.20% in 2002. Among males, the most common methods used were firearms and explosives, hanging, and poison, with a relative increase in hanging; whereas among females, poison was most common. A rising trend in suicide rates in Colombia was confirmed, especially among the productive segment of the population, which has resulted in a marked increase in YPLL.

Longevity in Slovenia: Past and potential gains in life expectancy by age and causes of death.

In Slovenia, longevity is increasing rapidly. From 1997 to 2014, life expectancy at birth increased by 7 and 5 years for men and women, respectively. This paper explores how this gain in life expectancy at birth can be attributed to reduced mortality from five major groups of causes of death by 5-year age groups. It also estimates potential future gains in life expectancy at birth. The importance of the five major causes of death was analysed by cause-elimination life tables. The total elimination of individual causes of death and a partial hypothetical adjustment of mortality to Spanish levels were analysed, along with age and cause decomposition (Pollard). During the 1997-2014 period, the increase in life expectancy at birth was due to lower mortality from circulatory diseases (ages above 60, both genders), as well as from lower mortality from neoplasms (ages above 50 years) and external causes (between 20 and 50 years) for men. However, considering the potential future gains in life expectancy at birth, by far the strongest effect can be attributed to lower mortality due to circulatory diseases for both genders. If Spanish mortality rates were reached, life expectancy at birth would increase by more than 2 years, again mainly because of lower mortality from circulatory diseases in very old ages. Life expectancy analyses can improve evidence-based decision-making and allocation of resources among different prevention programmes and measures for more effective disease management that can also reduce the economic burden of chronic diseases.

This clinical study was designed to evaluate mortality rate and the factors that may affect survival in neonatal surgery unit. Randomly chosen 300 (ß: 0.20) patients among 1,439 patients treated in neonatal surgery unit during years 1983 to 2009, were evaluated retrospectively. The patients were separated into three groups according to date of treatment; Group A: 1983 - 1995, Group B: 1996 - 2005 and Group C: 2005 - 2009. M/F ratios did not differ between non-survived and survived patient populations. Mortality rates were 37%, 22% and 13% in Group A, B, and C respectively (p < 0.001). Parenteral nutrition, maternal age, time until admission and gestational age did not affect mortality rate, however median age of newborn was lower in non-survived cases (1 day vs. 3 days, p < 0.001). Associating abnormality, low birth weight ( < 1,500 g), associating sepsis, need of globulin and requirement of respiratory support were determinants of lower survival (p < 0.001). The mortality rate for patients that underwent thoracotomy (42%) and laparotomy (41%) were higher than patients that underwent other operations (8%) and observation (10%) (p < 0.001). Diaphragmatic hernia had higher mortality rates than the other pathologies (p < 0.001). Survival rate is increasing to date in newborn pediatric surgery unit; it is independent from parenteral nutrition, maternal age, time to admission and gestational age however it is affected adversely by the age of patient, associating abnormality, low birth weight, presence of sepsis and requirement of respiratory support. Increase in survival could be related to various additional factors such as development of delicate respiratory support machines, broad spectrum antibiotics, hospital infection control teams, central venous catheters, use of TPN by central route, volume adjustable infusion pumps, monitoring devices, neonatal surgical techniques, prenatal diagnosis of pediatric surgical conditions and developments of environmental control methods in neonatal surgical units.

Unintentional falls mortality among elderly in the United States: time for action.

Fall injury is a leading cause of death and disability among older adults. The objective of this study is to identify the groups among the ≥ 65 population by age, gender, race, ethnicity and state of residence which are most vulnerable to unintentional fall mortality and report the trends in falls mortality in the United States. Using mortality data from the Centers for Disease Control and Prevention, the age specific and age-adjusted fall mortality rates were calculated by gender, age, race, ethnicity and state of residence for a five year period (2003-2007). Annual percentage changes in rates were calculated and linear regression using natural logged rates were used for time-trend analysis. There were 79,386 fall fatalities (rate: 40.77 per 100,000 population) reported. The annual mortality rate varied from a low of 36.76 in 2003 to a high of 44.89 in 2007 with a 22.14% increase (p=0.002 for time-related trend) during 2003-2007. The rates among whites were higher compared to blacks (43.04 vs. 18.83; p=0.01). While comparing falls mortality rate for race by gender, white males had the highest mortality rate followed by white females. The rate was as low as 20.19 for Alabama and as high as 97.63 for New Mexico. The relative attribution of falls mortality among all unintentional injury mortality increased with age (23.19% for 65-69 years and 53.53% for 85+ years), and the proportion of falls mortality was significantly higher among females than males (46.9% vs. 40.7%: p<0.001) and among whites than blacks (45.3% vs. 24.7%: p<0.001). The burden of fall related mortality is very high and the rate is on the rise; however, the burden and trend varied by gender, age, race and ethnicity and also by state of residence. Strategies will be more effective in reducing fall-related mortality when high risk population groups are targeted. Copyright © 2011 Elsevier Ltd. All rights reserved.

Relative deprivation of income is hypothesised to generate frustration and stress through upward social comparison with one's peers. If psychosocial stress is the mechanism, relative deprivation should be more strongly associated with specific health outcomes, such as cardiovascular disease (compared with other health outcomes, eg, non-tobacco-related cancer). We evaluated the association between relative income deprivation and mortality by leading causes, using a cohort of 21 031 community-dwelling adults aged 65 years or older. A baseline mail-in survey was conducted in 2003. Information on cause-specific mortality was obtained from death certificates. Our relative deprivation measure was the Yitzhaki Index, derived from the aggregate income shortfall for each person, relative to individuals with higher incomes in that person's reference group. Reference groups were defined according to gender, age group and same municipality of residence. We identified 1682 deaths during the 4.5 years of follow-up. A Cox regression demonstrated that, after controlling for demographic, health and socioeconomic factors including income, the HR for death from cardiovascular diseases per SD increase in relative deprivation was 1.50 (95% CI 1.09 to 2.08) in men, whereas HRs for mortality by cancer and other diseases were close to the null value. Additional adjustment for depressive symptoms and health behaviours (eg, smoking and preventive care utilisation) attenuated the excess risks for mortality from cardiovascular disease by 9%. Relative deprivation was not associated with mortality for women. The results partially support our hypothesised mechanism: relative deprivation increases health risks via psychosocial stress among men. Published by the BMJ Publishing Group Limited.

Injury and poisoning are a growing public health concern in China due to rapid economic growth, which has resulted in many cases with an injury-prone environment, such as overcrowded traffic, booming construction, and work-related stress. This study investigates the distribution and trends of deaths from injury and poisoning in Tianjin, China, by age, sex and urban/rural status, from 1999 to 2006. The study used data from the all-cause mortality surveillance system maintained by the Tianjin Centers for Disease Control and Prevention (CDC). Each death certificate recorded 53 variables. Cause of death was coded using the International Classification of Diseases (ICD). Standardized mortality rates and proportions of deaths were analyzed. Traffic accidents, suicide, poisoning, drowning and fall were the leading causes of fatal injuries in Tianjin from 1999 to 2006. Injury mortality rates were high in males, in rural areas, and in the older age groups. Despite low injury mortality rates, injury accounted for close to 50% of all deaths amongst the 5-29 year age group. Traffic accident mortality rates increased, although not significantly so, during the period from 1999 to 2006. Injury prevention and control is a high public health priority in Tianjin. Our detailed table on the number of deaths by causes of fatal injuries and by age group provides important information to set prevention strategies in the nurseries, schools, workplace and seniors homes. 2009 Elsevier Ltd.

Does a combination of lifestyle pressures and personality, as reflected in genre, lead to the early death of popular musicians? We explored overall mortality, cause of death, and changes in patterns of death over time and by music genre membership in popular musicians who died between 1950 and 2014. The death records of 13,195 popular musicians were coded for age and year of death, cause of death, gender, and music genre. Musician death statistics were compared with age-matched deaths in the US population using actuarial methods. Although the common perception is of a glamorous, free-wheeling lifestyle for this occupational group, the figures tell a very different story. Results showed that popular musicians have shortened life expectancy compared with comparable general populations. Results showed excess mortality from violent deaths (suicide, homicide, accidental death, including vehicular deaths and drug overdoses) and liver disease for each age group studied compared with population mortality patterns. These excess deaths were highest for the under-25-year age group and reduced chronologically thereafter. Overall mortality rates were twice as high compared with the population when averaged over the whole age range. Mortality impacts differed by music genre. In particular, excess suicides and liver-related disease were observed in country, metal, and rock musicians; excess homicides were observed in 6 of the 14 genres, in particular hip hop and rap musicians. For accidental death, actual deaths significantly exceeded expected deaths for country, folk, jazz, metal, pop, punk, and rock.

The authors compared generational and regional trends of premature mortality from ischemic heart disease (IHD) from 1969 to 1992 for persons aged 30-69 years. They selected Tokyo and Osaka prefectures as the most urbanized and compared them with the rest of Japan. The data were divided into two periods: period I (1969-1978, International Classification of Diseases, Eight Revision) and period II (1979-1992, International Classification of Diseases, Ninth Revision). In both populations, IHD mortality decreased for both sexes, but mortality from nonspecific heart disease remained constant in men and decreased in women. In Tokyo and Osaka prefectures, the percentage decline per year in IHD mortality for both sexes was significantly smaller in period II than in period I. However, in the rest of Japan, it did not decrease for either sex. Age-specific analysis showed that the percentage decline per year in period II was smallest for the group aged 30-49 years (men, 0.05%; women, 0.76%) in Tokyo and Osaka prefectures, while it was similar for all age groups in the rest of Japan. For men, the IHD mortality rate in 1991-1992 for those aged 30-49 years was higher in Tokyo and Osaka prefectures (9.4/100,000) than in the rest of Japan (5.4/100,000).

Most studies on inequalities in health and health-care focus on single indicators of social position, e.g. income or education. Recent research has suggested that multiple social circumstances need to be analysed simultaneously to disentangle their influence on health. In past decades mortality amenable to health-care, i.e. premature mortality that should not occur given timely and effective health-care, has increasingly been used to study the effect of health-care on health outcomes. This study elaborates the effect of social and regional deprivation and unemployment on the association between income and mortality amenable to health-care in Finland. Individual-level data for deaths were gathered by disease category between 1992 and 2008 for the resident Finnish population aged 25 to 59 years. Differences in amenable mortality and changes over time were assessed using individual-level linked register data. We used gender- and age-standardised rates and Poisson regression models to examine the simultaneous effect of these indicators on amenable mortality. Altogether 22,663 persons aged 25-59 years died from causes amenable to health-care during the study period. An inverse pattern was found in amenable mortality for income. The mortality rate in the lowest income quintile was 98 (93-104) per 100,000 in the period 1991-1996 while in the highest group the figure was 40 (38-42) for the same period. Whereas the level of amenable mortality decreased, mortality differences between income groups steepened and amenable mortality increased in the lowest income group towards the end of the study period. Those in poor labour market position or living alone had significantly larger income differences in amenable mortality. Risk of regional deprivation was not associated with amenable mortality. In order to prevent and treat at an early phase conditions that otherwise may lead to premature and unnecessary deaths more attention should be focused on groups with increased social and economic deprivation risk in municipal health centres with the aim at improving access to primary care. Our results also call for joint action by both health-care and social services, since health services alone cannot deal with the risks posed by accumulating social disadvantage.

Alcohol-related deaths contribute to socioeconomic differentials in mortality in Sweden.

Hemström, Orjan

This study aims at estimating the contribution of alcohol to socioeconomic mortality differentials in Sweden. Data were obtained from a Census-linked Deaths Registry. Participants in the 1980 and 1990 censuses were included with a follow-up of mortality 1990-1995. Socioeconomic status was assigned from occupation in 1990 or 1980. Alcohol-related deaths were defined from underlying or contributory causes. Poison regressions were applied to compute age-adjusted mortality rate ratios for all-causes, alcohol-related and other causes among 30-79-year-olds. The contribution of alcohol to mortality differentials was calculated from absolute differences. Around 5% (9,547) of all deaths were alcohol-related (30-79 years). For both sexes, manual workers, lower nonmanuals, entrepreneurs and unclassifiable groups had significantly higher alcohol-related mortality than did upper nonmanuals. Male farmers had significantly lower such mortality. The contribution of alcohol to excess mortality over that of upper nonmanuals was greatest among middle-aged (40-59 years) men who were manual workers or who belonged to a group of 'unclassifiable & others' (25-35%). It was of considerable size also for middle-aged lower nonmanuals (both sexes), male entrepreneurs, female manual workers and 'unclassifiable & others'. Among men, the total contribution of alcohol (30-79 years) was estimated at 16% for manual workers, 10% for lower nonmanuals and 7% for entrepreneurs; and among women, 6% (manual workers, lower nonmanuals) and 3% (entrepreneurs). Although deaths related to alcohol were probably underreported (e.g. accidents), alcohol clearly contributes to socioeconomic mortality differentials in Sweden. The size of this contribution depends strongly on age (peak among the middle-aged) and gender (greatest among men).

South Africa has one of the highest HIV/AIDS prevalence rates in the world. It is estimated that 5.38 million South Africans are living with HIV/AIDS. In addition, new infections among adults aged 15+ were reportedly 316 900 in 2011. New infections among children (0-14 years old) was also high in 2011 at 63 600. This paper examines South Africa's mortality due to HIV/AIDS among the youth (15-34 years old). This age group is of fundamental importance to the economic and social development of the country. However, the challenges of youth development remain vast and incomparable. One of these challenges is the impact of HIV/AIDS on mortality. Life table techniques are used to estimate among others, sex differentials in death rates for the youth population, probability of dying from HIV/AIDS before the age of 35 and life expectancy should HIV/AIDS be eradicated from the population. The study used data from the National Registry of Deaths, as collated by Statistics South Africa from 2001 to 2009. Results show that youth mortality due to HIV/AIDS has remained consistently higher among older youths than in younger ones. By sex, mortality due to this cause has also remained consistent over the period, with mortality due to HIV/AIDS being higher among females than males. Cause-specific mortality rates and proportional mortality ratios reflect the increased mortality of older youth (especially 30-34 years old) and females within the South African population. Probability of dying from HIV/AIDS shows that over the period, fluctuations in likelihood of mortality have occurred, but for both males and females (of all age groups) the chances of dying from this cause decreased in 2007-2009.

Household air pollution (HAP) mainly from cooking fuel is one of the major causes of respiratory illness and deaths among young children in low and middle-income countries like Pakistan. This study investigates for the first time the association between HAP from cooking fuel and under-five mortality using the 2013 Pakistan Demographic and Health Survey (PDHS) data. Multi-level logistic regression models were used to examine the association between HAP and under-five mortality in a total of 11,507 living children across four age-groups (neonatal aged 0-28 days, post-neonatal aged 1-11 months, child aged 12-59 months and under-five aged 0-59 months). Use of cooking fuel was weakly associated with total under-five mortality (OR = 1.22, 95%CI = 0.92-1.64, P = 0.170), with stronger associations evident for sub-group analyses of children aged 12-59 months (OR = 1.98, 95%CI = 0.75-5.25, P = 0.169). Strong associations between use of cooking fuel and mortality were evident (ORs >5) in those aged 12-59 months for households without a separate kitchen using polluting fuels, and in children whose mother never breastfed. The results of this study suggest that HAP from cooking fuel is associated with a modest increase in the risk of death among children under five years of age in Pakistan, but particularly in those aged 12-59 months, and those living in poorer socioeconomic conditions. To reduce exposure to cooking fuel which is a preventable determinant of under-five mortality in Pakistan, the challenge remains to promote behavioural interventions such as breastfeeding in infancy period, keeping young children away from the cooking area, and improvements in housing and kitchen design.

Occupation- and industry-based risks for stroke and ischemic heart disease may vary among Japanese working-aged men. We examined the differences in mortality rates between stroke and ischemic heart disease by occupation and industry among employed Japanese men aged 25-59 years. In 2010, we obtained occupation- and industry-specific vital statistics data from the Japanese Ministry of Health, Labour, and Welfare dataset. We analyzed data for Japanese men who were aged 25-59 years in 2010, grouped in 5-year age intervals. We estimated the mortality rates of stroke and ischemic heart disease in each age group for occupation and industry categories as defined in the national census. We did not have detailed individual-level variables. We used the number of employees in 2010 as the denominator and the number of events as the numerator, assuming a Poisson distribution. We conducted separate regression models to estimate the incident relative risk for stroke and ischemic heart disease for each category compared with the reference categories "sales" (occupation) and "wholesale and retail" (industry). When compared with the reference groups, we found that occupations and industries with a relatively higher risk of stroke and ischemic heart disease were: service, administrative and managerial, agriculture and fisheries, construction and mining, electricity and gas, transport, and professional and engineering. This suggests there are occupation- and industry-based mortality risk differences of stroke and ischemic heart disease for Japanese working-aged men. These differences in risk might be explained to factors associated with specific occupations or industries, such as lifestyles or work styles, which should be explored in further research. The mortality risk differences of stroke and ischemic heart disease shown in the present study may reflect an excessive risk of Karoshi (death from overwork).

To analyze the effect of the type of malnutrition, sex, age and the presence of edema upon all-cause mortality in children under 5 years of age. A cross-sectional study was conducted during 2010 and 2011 in Swaziland. Sex, age, weight and height were taken to classify nutritional status according to the 2006 WHO growth standards: stunting (low height for age), wasting (low weight for height or low body mass index for age) and underweight (low weight for age). The sample (309 boys and 244 girls under 5 years of age) was analyzed by sex and age groups (under and equal/over 12 months). The association between variables was evaluated using the χ 2 test. Cox regression analysis (HR, 95% CI) was used to assess the likelihood of mortality. The mortality risk in malnourished children under one year of age was lower among females and increased in the presence of severe edema. Wasting combined with underweight increased the mortality risk in children under 12 months of age 5-fold, versus 11-fold in older children. The combination of stunting, wasting and underweight was closely associated to mortality. Stunting alone (not combined with wasting) did not significantly increase the mortality risk. Sex, severe edema and wasting are predictors of mortality in malnourished children. Regardless of these factors, children with deficiencies referred to weight for height and weight for age present a greater mortality risk in comparison with children who present stunting only.

The aims of this study were to verify the distribution of births of captive maned wolves Chrysocyon brachyurus and the causes of their deaths during the period from 1980 to 1998, based on the registry of births and deaths in the International Studbook for Maned Wolves. To determine birth distribution and average litter size, 361 parturitions were analyzed for the 1989-98 period. To analyze causes of mortality, the animals were divided into four groups: 1. pups born in captivity that died prior to one year of age; 2. animals born in captivity that died at more than one year of age; 3. animals captured in the wild that died at any age; and 4. all animals that died during the 1980-98 period. In group 1, the main causes of mortality were parental incompetence (67%), infectious diseases, (9%) and digestive system disorders (5%). The average mortality rate for pups was 56%. Parental incompetence was responsible for 95% of pup deaths during the first week of life. In group 2, the main causes were euthanasia (18%) and disorders of the genitourinary (10%) and digestive systems (8%). Euthanasia was implemented due to senility, congenital disorders, degenerative diseases, and trauma. In group 3, the main causes were digestive system disorders (12%), infectious diseases (10%), and lesions or accidents (10%). The main causes of mortality of maned wolves in captivity (group 4) were parental incompetence (38%), infectious diseases (9%), and digestive system disorders (7%).

traumatic brain injury (TBI) is a significant public health problem. Developed countries report a significant increase of TBI in older adults in the past decades. The objective of this study was to investigate the changes in TBI-related mortality in older Austrians (65 years or older) between 1980 and 2012 (33 years) and to identify possible causes for these changes. data from Statistics Austria on mortality in Austria between 1980 and 2012 were screened and data on TBI-related mortality in adults aged 65 and older were extracted and analysed, based on the diagnostic codes of the International Classification of Diseases, 10th and 9th revision. Mortality rates were calculated for 5-year age groups; standardized mortality rates were calculated for the total. Mechanism of injury was analysed for all events, both sexes and individual age groups. between 1980 and 2012, 16,204 people aged 65 or older died from TBI in Austria; 61% of these were male. Fatal TBI cases and mortality rates increased in the oldest age groups (80 years or older). Half of the fatal TBI cases were caused by falls, 22% by traffic accidents and 17% by suicides. Rate of fall-related fatal TBI increased and rate of traffic accident-related fatal TBI decreased with age. preventive measures introduced in the past decades in the developed countries have contributed to a decrease in traffic injuries. However, falls in the older population are on the rise, mainly due to ageing of the population, throughout the reported period. It is important to take preventive measures to stop the epidemics of fall-related TBIs and fatalities in older adults. © The Author 2014.

Background National Central Cancer Registry of China (NCCRC) updated nationwide cancer statistics using population-based cancer registry data in 2014 collected from all available cancer registries. Methods In 2017, 449 cancer registries submitted cancer registry data in 2014, among which 339 registries’ data met the criteria of quality control and were included in analysis. These cancer registries covered 288,243,347 population, accounting for about 21.07% of the national population in 2014. Numbers of nationwide new cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by area, sex, age group and cancer type. The world Segi’s population was applied for age-standardized rates. Results A total of 3,804,000 new cancer cases were diagnosed, the crude incidence rate was 278.07/100,000 (301.67/100,000 in males, 253.29/100,000 in females) and the age-standardized incidence rate by world standard population (ASIRW) was 186.53/100,000. Calculated age-standardized incidence rate was higher in urban areas than in rural areas (191.6/100,000 vs. 179.2/100,000). South China had the highest cancer incidence rate while Southwest China had the lowest incidence rate. Cancer incidence rate was higher in female for population between 20 to 54 years but was higher in male for population younger than 20 years or over 54 years. A total of 2,296,000 cancer deaths were reported, the crude mortality rate was 167.89/100,000 (207.24/100,000 in males, 126.54/100,000 in females) and the age-standardized mortality rate by world standard population (ASMRW) was 106.09/100,000. Calculated age-standardized mortality rate was higher in rural areas than in urban areas (110.3/100,000 vs. 102.5/100,000). East China had the highest cancer mortality rate while North China had the lowest mortality rate. The mortality rate in male was higher than that in female. Common cancer types and major causes of cancer death differed between age group and sex. Conclusions Heavy cancer burden and its disparities between area, sex and age group pose a major challenge to public health in China. Nationwide cancer registry plays a crucial role in cancer prevention and control. PMID:29545714

The aim of this study is to determine the incidence, associated factors, and 30-day mortality of patients with heart failure (HF) after ST elevation myocardial infarction (STEMI) in Peru. Observational, cohort, multicentre study was conducted at the national level on patients enrolled in the Peruvian registry of STEMI, excluding patients with a history of HF. A comparison was made with the epidemiological characteristics, treatment, and 30 day-outcome of patients with (Group 1) and without (Group 2) heart failure after infarction. Of the 388 patients studied, 48.7% had symptoms of HF, or a left ventricular ejection fraction <40% after infarction (Group 1). Age>75 years, anterior wall infarction, and the absence of electrocardiographic signs of reperfusion were the factors related to a higher incidence of HF. The hospital mortality in Group 1 was 20.6%, and the independent factors related to higher mortality were age>75 years, and the absence of electrocardiographic signs of reperfusion. Heart failure complicates almost 50% of patients with STEMI, and is associated with higher hospital and 30-day mortality. Age greater than 75 years and the absence of negative T waves in the post-reperfusion ECG are independent factors for a higher incidence of HF and 30-day mortality.

As a result of the increasing of life expectancy, the incidence of pathologies that can lead to operation for bowel obstruction is also increasing. Comorbidities and reduced physiological reserve can decrease elderly patients' ability to tolerate operations especially in an emergency context. We retrospectively evaluated the treatment and outcomes of a cohort of patients aged more than 85 years who underwent emergency surgery for intestinal occlusion. 278 patients who were admitted to our Institution and operated for acute bowel obstruction have been included in our study. We divided the study population in 2 groups (group A: patients aged > 85 years old; group B patients aged ≤ 85 years). We evaluated the differences between the two groups in terms of intestinal occlusion aetiology, surgical procedures, morbidity and mortality rates. Group A consisted of 57 patients, group B of 221; elderly patients trend in ASA score classification was significantly towards high risk for elderly group; statistical analysis did not show differences in terms of bowel obstruction aetiology (except colon volvulus, more frequent in advanced age), type of procedure, duration of hospital stay, procedure - related complication rate. Perioperative mortality was significantly higher in elderly group, due to the mayor incidence of cardiovascular and respiratory fatal events directly related to pre - existing comorbidities. Despite the high surgical risk, early diagnosis and treatment of the obstructive disease can lead to achieve encouraging outcomes also in extremely advanced age; an aggressive evaluation of comorbidies and the cardio - respiratory risks reduction, when possible, could be useful in improve postoperative outcomes in terms of mortality.

The injury mortality burden in Guinea

PubMed Central

2012-01-01

Background The injury mortality burden of Guinea has been rarely addressed. The paper aimed to report patterns of injury mortality burden in Guinea. Methods We retrieved the mortality data from the Guinean Annual Health Statistics Report 2007. The information about underlying cause of deaths was collected based on Guinean hospital discharge data, Hospital Mortuary and City Council Mortuary data. The causes of death are coded in the 9th International Classification of Diseases (ICD-9). Multivariate Poisson regression was used to test the impacts of sex and age on mortality rates. The statistical analyses were performed using Statatm 10.0. Results In 2007, 7066 persons were reported dying of injuries in Guinea (mortality: 72.8 per 100,000 population). Transportation, fire/burn, falls, homicide and drowning were the five leading causes of fatal injuries for the whole population, accounting for 37%, 22%, 12%, 10% and 6% of total deaths, respectively. In general, age-specific injury causes displayed similar patterns of the whole population except that poisoning replaced falls as a leading cause among children under five years old. Males were at 30-50% more risk of dying from six commonest causes than females and old age groups had higher injury mortality rates than younger age groups. Conclusion Transportation, fire/burn, falls, homicide, and drowning accounted for the majority of total injury mortality burden in Guinea. Males and old adults were high-risk population of fatal injuries and should be targeted by injury prevention. Lots of work is needed to improve weak capacities for injury control in order to reduce the injury mortality burden. PMID:22937768

Self-perceptions of own social position are potentially a key aspect of socioeconomic inequalities in health, but their association with mortality remains poorly understood. We examined whether subjective social status (SSS), a measure of the self-perceived element of social position, was associated with mortality and its role in the associations between objective socioeconomic position (SEP) measures and mortality. We used Cox regression to model the associations between SSS, objective SEP measures and mortality in a sample of 9972 people aged ≥ 50 years from the English Longitudinal Study of Ageing over a 10-year follow-up (2002-2013). Our findings indicate that SSS was associated with all-cause, cardiovascular, cancer and other mortality. A unit decrease in the 10-point continuous SSS measure increased by 24 and 8% the mortality risk of people aged 50-64 and ≥ 65 years, respectively, after adjustment for age, sex and marital status. The respective estimates for cardiovascular mortality were 36 and 11%. Adjustment for all covariates fully explained the association between SSS and cancer mortality, and partially the remaining associations. In people aged 50-64 years, SSS mediated to a varying extent the associations between objective SEP measures and all-cause mortality. In people aged ≥ 65 years, SSS mediated to a lesser extent these associations, and to some extent was associated with mortality independent of objective SEP measures. Nevertheless, in both age groups, wealth partially explained the association between SSS and mortality. In conclusion, SSS is a strong predictor of mortality at older ages, but its role in socioeconomic inequalities in mortality appears to be complex.

Acute upper gastrointestinal bleeding (UGIB) affects large number of elderly with high rates of morbidity and mortality. Early identification and management of the factors predicting in-hospital mortality might decrease mortality. This study was conducted to identify the causes of acute UGIB and the predictors of in-hospital mortality in elderly Egyptian patients.286 elderly patients with acute UGIB were divided into: bleeding variceal group (161 patients) and bleeding nonvariceal group (125 patients). Patients' monitoring was done during hospitalization to identify the risk factors that might predict in-hospital mortality in elderly.Variceal bleeding was the most common cause of acute UGIB in elderly Egyptian patients. In-hospital mortality rate was 8.74%. Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding were the predictors of in-hospital mortality.Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding should be considered when triaging those patients for immediate resuscitation, close observation, and early treatment.

The purpose of this study was to update and analyze data on mortality trend due to chronic obstructive pulmonary disease (COPD) in Brazil. Initially, the specific COPD mortality rates were calculated from 1989 to 2009 using data collected from DATASUS (Departamento de Informática do SUS - Brazilian Health System Database). Then, the polynomial regression models from the observed functional relation were estimated based on mortality coefficients and study years. We verified that the general mortality rates due to COPD in Brazil showed an increasing trend from 1989 to 2004, and then decreased. Both genders showed the same increasing tendencies until 2004 and decreased thereafter. The age group under 35 years old showed a linear decreasing trend. All other age groups showed quadratic tendencies, with increases until the years of 1998-1999 and then decreasing. The South and Southeast regions showed the highest COPD mortality rates with increasing trends until the years 2001-2002 and then decreased. The North, Northeast and Central-West regions showed lower mortality rates but increasing trend. This is the first report of COPD mortality stabilization in Brazil since 1980.

Background Injuries are an increasingly important cause of death in children worldwide, yet injury mortality is highly preventable. Determining patterns and trends in child injury mortality can identify groups at particularly high risk. We compare trends in child deaths due to injury in four UK countries, between 1980 and 2010. Methods We obtained information from death certificates on all deaths occurring between 1980 and 2010 in children aged 28 days to 18 years and resident in England, Scotland, Wales or Northern Ireland. Injury deaths were defined by an external cause code recorded as the underlying cause of death. Injury mortality rates were analysed by type of injury, country of residence, age group, sex and time period. Results Child mortality due to injury has declined in all countries of the UK. England consistently experienced the lowest mortality rate throughout the study period. For children aged 10 to 18 years, differences between countries in mortality rates increased during the study period. Inter-country differences were largest for boys aged 10 to 18 years with mortality rate ratios of 1.38 (95% confidence interval 1.16, 1.64) for Wales, 1.68 (1.48, 1.91) for Scotland and 1.81 (1.50, 2.18) for Northern Ireland compared with England (the baseline) in 2006–10. The decline in mortality due to injury was accounted for by a decline in unintentional injuries. For older children, no declines were observed for deaths caused by self-harm, by assault or from undetermined intent in any UK country. Conclusion Whilst child deaths from injury have declined in all four UK countries, substantial differences in mortality rates remain between countries, particularly for older boys. This group stands to gain most from policy interventions to reduce deaths from injury in children. PMID:23874585

Regions of the Russian Federation differ in climatic-geographic, medical-demographic and social-economic situations. One of the regions with distinct peculiarities is the Republic of Sakha (Yakutia). Ranking first by the territory (3,103.2 thousand sq x km), Yakutia is on the 81th place by the population density among regions of the Russian Federation (0.3 people per 1 km2).Yakutia is one of the most isolated and inaccessible regions of the world: 90% of the territory lacks all-the-year-round transportation. Regions of the republic, as well, differ significantly in the climatic conditions and the levels of social-economic development, which influences the population health indicators, including mortality. This survey aimed to study the trends of mortality in the working-age population in different groups of regions. To do this, basing on the statistical data, we compared the levels, trends and structure of mortality in 1990-2012. It was established that the different groups of regions show a significant variation in the working-age population mortality, depending on the social-economic conditions. Since 2000, the Arctic group of regions has demonstrated higher mortality in working-age men and women, especially of cardiovascular and digestive system diseases, and external causes. Lying beyond the Arctic Circle, these regions have severe conditions and a relatively low level of social-economic development. As for the rural regions, despite the relatively favourabe situation, they also show a high level of mortality of external causes. The industrial regions are characterized by higher social-economic development, better transport infrastructure, a satisfactory material base of medical institutions. They also have sufficient resources of health institutions, including the staff and modern equipment for treatment and diagnostics, as well as, which is critical, the full range of medical specialists. Thus, these regions demonstrate lower population mortality; however, there is still mortality of infectious diseases, neoplasms, and respiratory diseases.

The effect of modifying lifestyle at middle age on mortality has been sparsely examined. Men and women aged 50-54 years randomised to the control group (no intervention) in the population-based Norwegian Colorectal Cancer Prevention trial were asked to fill in lifestyle questionnaires in 2001 and 2004. Lifestyle scores were estimated ranging from 0 (poorest) to 4 (best) based on health recommendations (non-smoking, daily physical activity, body mass index <25.0 kg/m 2 and healthy diet). Outcomes were all-cause, cancer and cardiovascular mortality before 31 December 2013. Of the 6886 attainable individuals included in the study, 4211 (61%) responded to the baseline questionnaire in 2001. After a median follow-up of 12.3 years, 226 (5.4%) of the baseline questionnaire responders died; 110 (49%) from cancer and 32 (14%) from cardiovascular disease. For each increment in lifestyle score in 2001, a 21% lower all-cause mortality was observed (HR 0.79, 95% CI 0.67 to 0.94, adjusted for age, sex, occupational working hours and chronic disease or pain during 3 years before enrolment). A one-point increase in lifestyle score from 2001 to 2004 was associated with a 38% reduction in all-cause mortality (adjusted HR 0.62, CI 0.45 to 0.84). The group reporting lifestyle change from score 0-1 (unfavourable) in 2001 to score 2-4 (favourable) in 2004 had 4.8 fewer deaths per 1000 person years, compared with the group maintaining an 'unfavourable' lifestyle (adjusted HR 0.31, CI 0.13 to 0.70 for all-cause mortality). Favourable lifestyle changes at age 50-60 years may prevent early death. NCT00119912; pre-results. Published by the BMJ Publishing Group Limited.

In addition to protecting against measles, measles vaccine (MV) may have beneficial nonspecific effects. We tested the effect of an additional early MV on mortality and measles antibody levels. Children aged 4-7 months at rural health and demographic surveillance sites in Burkina Faso and Guinea-Bissau were randomized 1:1 to an extra early standard dose of MV (Edmonston-Zagreb strain) or no extra MV 4 weeks after the third diphtheria-tetanus-pertussis-hepatitis B-Haemophilus influenzae type b vaccine. All children received routine MV at 9 months. We assessed mortality through home visits and compared mortality from enrollment to age 3 years using Cox proportional hazards models, censoring for subsequent nontrial MV. Subgroups of participants had blood sampled to assess measles antibody levels. Among 8309 children enrolled from 18 July 2012 to 3 December 2015, we registered 145 deaths (mortality rate: 16/1000 person-years). The mortality was lower than anticipated and did not differ by randomization group (hazard ratio, 1.05; 95% confidence interval, 0.75-1.46). At enrollment, 4% (16/447) of children in Burkina Faso and 21% (90/422) in Guinea-Bissau had protective measles antibody levels. By age 9 months, no measles-unvaccinated/-unexposed child had protective levels, while 92% (306/333) of early MV recipients had protective levels. At final follow-up, 98% (186/189) in the early MV group and 97% (196/202) in the control group had protective levels. Early MV did not reduce all-cause mortality. Most children were susceptible to measles infection at age 4-7 months and responded with high antibody levels to early MV. NCT01644721.

Mortality Measurement at Advanced Ages: A Study of the Social Security Administration Death Master File

Accurate estimates of mortality at advanced ages are essential to improving forecasts of mortality and the population size of the oldest old age group. However, estimation of hazard rates at extremely old ages poses serious challenges to researchers: (1) The observed mortality deceleration may be at least partially an artifact of mixing different birth cohorts with different mortality (heterogeneity effect); (2) standard assumptions of hazard rate estimates may be invalid when risk of death is extremely high at old ages and (3) ages of very old people may be exaggerated. One way of obtaining estimates of mortality at extreme ages is to pool together international records of persons surviving to extreme ages with subsequent efforts of strict age validation. This approach helps researchers to resolve the third of the above-mentioned problems but does not resolve the first two problems because of inevitable data heterogeneity when data for people belonging to different birth cohorts and countries are pooled together. In this paper we propose an alternative approach, which gives an opportunity to resolve the first two problems by compiling data for more homogeneous single-year birth cohorts with hazard rates measured at narrow (monthly) age intervals. Possible ways of resolving the third problem of hazard rate estimation are elaborated. This approach is based on data from the Social Security Administration Death Master File (DMF). Some birth cohorts covered by DMF could be studied by the method of extinct generations. Availability of month of birth and month of death information provides a unique opportunity to obtain hazard rate estimates for every month of age. Study of several single-year extinct birth cohorts shows that mortality trajectory at advanced ages follows the Gompertz law up to the ages 102–105 years without a noticeable deceleration. Earlier reports of mortality deceleration (deviation of mortality from the Gompertz law) at ages below 100 appear to be artifacts of mixing together several birth cohorts with different mortality levels and using cross-sectional instead of cohort data. Age exaggeration and crude assumptions applied to mortality estimates at advanced ages may also contribute to mortality underestimation at very advanced ages. PMID:22308064

In the past decades, mortality of female gender related cancers declined in Switzerland and other developed countries. Differences in the decrease and in spatial patterns within Switzerland have been reported according to urbanisation and language region, and remain controversial. We aimed to investigate geographical and temporal trends of breast, ovarian, cervical and uterine cancer mortality, assess whether differential trends exist and to provide updated results until 2011. Breast, ovarian, cervical and uterine cancer mortality and population data for Switzerland in the period 1969-2011 was retrieved from the Swiss Federal Statistical office (FSO). Cases were grouped into <55 year olds, 55-74 year olds and 75+ year olds. The geographical unit of analysis was the municipality. To explore age- specific spatio-temporal patterns we fitted Bayesian hierarchical spatio-temporal models on subgroup-specific death rates indirectly standardized by national references. We used linguistic region and degree of urbanisation as covariates. Female cancer mortality continuously decreased in terms of rates in all age groups and cancer sites except for ovarian cancer in 75+ year olds, especially since 1990 onwards. Contrary to other reports, we found no systematic difference between language regions. Urbanisation as a proxy for access to and quality of medical services, education and health consciousness seemed to have no influence on cancer mortality with the exception of uterine and ovarian cancer in specific age groups. We observed no obvious spatial pattern of mortality common for all cancer sites. Rate reduction in cervical cancer was even stronger than for other cancer sites. Female gender related cancer mortality is continuously decreasing in Switzerland since 1990. Geographical differences are small, present on a regional or canton-overspanning level, and different for each cancer site and age group. No general significant association with cantonal or language region borders could be observed.

Bariatric surgery is effective in reducing all-cause and cause-specific long-term mortality. Whether the long-term mortality benefit of surgery applies to all ages at which surgery is performed is not known. To examine whether gastric bypass surgery is equally effective in reducing mortality in groups undergoing surgery at different ages. All-cause and cause-specific mortality rates and hazard ratios (HRs) were estimated from a retrospective cohort within 4 categories defined by age at surgery: younger than 35 years, 35 through 44 years, 45 through 54 years, and 55 through 74 years. Mean follow-up was 7.2 years. Patients undergoing gastric bypass surgery seen at a private surgical practice from January 1, 1984, through December 31, 2002, were studied. Data analysis was performed from June 12, 2013, to September 6, 2015. A cohort of 7925 patients undergoing gastric bypass surgery and 7925 group-matched, severely obese individuals who did not undergo surgery were identified through driver license records. Matching criteria included year of surgery to year of driver license application, sex, 5-year age groups, and 3 body mass index categories. Roux-en-Y gastric bypass surgery. All-cause and cause-specific mortality compared between those undergoing and not undergoing gastric bypass surgery using HRs. Among the 7925 patients who underwent gastric bypass surgery, the mean (SD) age at surgery was 39.5 (10.5) years, and the mean (SD) presurgical body mass index was 45.3 (7.4). Compared with 7925 matched individuals not undergoing surgery, adjusted all-cause mortality after gastric bypass surgery was significantly lower for patients 35 through 44 years old (HR, 0.54; 95% CI, 0.38-0.77), 45 through 54 years old (HR, 0.43; 95% CI, 0.30-0.62), and 55 through 74 years old (HR, 0.50; 95% CI, 0.31-0.79; P < .003 for all) but was not lower for those younger than 35 years (HR, 1.22; 95% CI, 0.82-1.81; P = .34). The lack of mortality benefit in those undergoing gastric bypass surgery at ages younger than 35 years primarily derived from a significantly higher number of externally caused deaths (HR, 2.53; 95% CI, 1.27-5.07; P = .009), particularly among women (HR, 3.08; 95% CI, 1.4-6.7; P = .005). Patients undergoing gastric bypass surgery had a significantly lower age-related increase in mortality than severely obese individuals not undergoing surgery (P = .001). Gastric bypass surgery was associated with improved long-term survival for all patients undergoing surgery at ages older than 35 years, with externally caused deaths only elevated in younger women. Gastric bypass surgery is protective against mortality even for older patients and also reduces the age-related increase in mortality observed in severely obese individuals not undergoing surgery.

Recent studies of old-age mortality trends assess whether longevity improvements over time are linked to increasing compression of mortality at advanced ages. The historical backdrop of these studies is the long-term improvements in a population's socioeconomic resources that fueled longevity gains. We extend this line of inquiry by examining whether socioeconomic differences in longevity within a population are accompanied by old-age mortality compression. Specifically, we document educational differences in longevity and mortality compression for older men and women in the United States. Drawing on the fundamental cause of disease framework, we hypothesize that both longevity and compression increase with higher levels of education and that women with the highest levels of education will exhibit the greatest degree of longevity and compression. Results based on the Health and Retirement Study and the National Health Interview Survey Linked Mortality File confirm a strong educational gradient in both longevity and mortality compression. We also find that mortality is more compressed within educational groups among women than men. The results suggest that educational attainment in the United States maximizes life chances by delaying the biological aging process. PMID:22556045

To evaluate time trends in surgical resection rates and operative mortality in older adults diagnosed with locoregional pancreatic cancer and to determine the effect of age on surgical resection rates and 2-year survival after surgical resection. Retrospective cohort study using data from the Surveillance, Epidemiology, and End Results (SEER) and linked Medicare claims database (1992-2005). Secondary data analysis of population-based tumor registry and linked claims data. Medicare beneficiaries aged 66 and older diagnosed with locoregional pancreatic cancer (N=9,553), followed from date of diagnosis to time of death or censorship. Percentage of participants undergoing surgical resection, 30-day operative mortality after resection, and 2-year survival according to age group. Surgical resection rates increased significantly, from 20% in 1992 to 29% in 2005, whereas 30-day operative mortality rates decreased from 9% to 5%. After controlling for multiple factors, participants were less likely to be resected with older age. Resection was associated with lower hazard of death, regardless of age, with hazard ratios of 0.46, 0.51, 0.47, 0.43, and 0.35 for resected participants younger than 70, 70 to 74, 75 to 79, 80 to 84, and 85 and older respectively compared with unresected participants younger than 70 (P<.001). With older age, fewer people with pancreatic cancer undergo surgical resection, even after controlling for comorbidity and other factors. This study demonstrated increased resection rates over time in all age groups, along with lower surgical mortality rates. Despite previous reports of greater morbidity and mortality after pancreatic resection in older adults, the benefit of resection does not diminish with older age in selected people. © 2011, Copyright the Authors.

The sequence of vaccinations and increased female mortality after high-titre measles vaccine: trials from rural Sudan and Kinshasa.

West African studies have hypothesized that increased female mortality after high-titre measles vaccine (HTMV) was due to subsequent diphtheria-tetanus-pertussis (DTP) and inactivated polio vaccine (IPV) vaccinations. We tested two deductions from this hypothesis in HTMV studies from rural Sudan and Kinshasa; first, there should be no excess female mortality for HTMV recipients when DTP was not given after HTMV and second, excess female mortality should only be found among those children who received DTP after HTMV. The Sudanese trial randomised 510 children to Edmonston-Zagreb (EZ) HTMV, Connaught HTMV or a control vaccine (meningococcal). Both the Connaught HTMV and the control group received standard measles vaccine at 9 months. In the Kinshasa study 1023 children received one dose of HTMV at 6 months or two doses at 312 and 912 months of age. First, the Sudan trial is one of the few randomised studies of measles vaccine; the EZ HTMV group had lower mortality between 5 and 9 months of age than controls, the mortality ratio (MR) being 0.00 (p = 0.030). This effect was not due to prevention of measles infection. Second, both studies provided evidence that HTMV per se was associated with low mortality. In a combined analysis comparing both HTMV groups with controls, the HTMV groups had a MR of 0.09 (0.01-0.71) between 5 and 9 months of age. In Kinshasa, the HTMV recipients who did not receive simultaneous DTP had an annual mortality rate of only 1.0% between 6 months and 3 years of age. Third, the female-male MR was related to subsequent DTP vaccinations. In Kinshasa, the female-male MR was only 0.40 (0.13-1.27) among the HTMV recipients who did not receive further doses of DTP. In Sudan, the female-male mortality ratio in the EZ group was 3.89 (95% CI 1.02-14.83) and the female-male MR increased with number of doses of DTP likely to have been given during follow-up (trend, p = 0.043). Fourth, in Kinshasa, mortality was higher among children who had received HTMV and DTP simultaneously than among children who had received HTMV alone (MR = 5.38 (1.37-21.2)). Measles vaccine is associated with non-specific beneficial effects. When not given with DTP, HTMV per se was associated with low mortality. Increased female mortality was not found among children who did not receive DTP after HTMV. Hence, our deductions were supported and the sequence or combination of vaccinations may have an effect on sex-specific mortality patterns in low-income countries.

A single flexible sigmoidoscopy at around the age of 60 years has been proposed as an effective strategy for colorectal cancer (CRC) screening. We conducted a randomized controlled trial to evaluate the effect of flexible sigmoidoscopy screening on CRC incidence and mortality. A questionnaire to assess the eligibility and interest in screening was mailed to 236,568 men and women, aged 55-64 years, who were randomly selected from six trial centers in Italy. Of the 56,532 respondents, interested and eligible subjects were randomly assigned to the intervention group (invitation for flexible sigmoidoscopy; n = 17,148) or the control group (no further contact; n = 17,144), between June 14, 1995, and May 10, 1999. Flexible sigmoidoscopy was performed on 9911 subjects. Intention-to-treat and per-protocol analyses were performed to compare the CRC incidence and mortality rates in the intervention and control groups. Per-protocol analysis was adjusted for noncompliance. A total of 34,272 subjects (17,136 in each group) were included in the follow-up analysis. The median follow-up period was 10.5 years for incidence and 11.4 years for mortality; 251 subjects were diagnosed with CRC in the intervention group and 306 in the control group. Overall incidence rates in the intervention and control groups were 144.11 and 176.43, respectively, per 100,000 person-years. CRC-related death was noted in 65 subjects in the intervention group and 83 subjects in the control group. Mortality rates in the intervention and control groups were 34.66 and 44.45, respectively, per 100,000 person-years. In the intention-to-treat analysis, the rate of CRC incidence was statistically significantly reduced in the intervention group by 18% (rate ratio [RR] = 0.82, 95% confidence interval [CI] = 0.69 to 0.96), and the mortality rate was non-statistically significantly reduced by 22% (RR = 0.78; 95% CI = 0.56 to 1.08) compared with the control group. In the per-protocol analysis, both CRC incidence and mortality rates were statistically significantly reduced among the screened subjects; CRC incidence was reduced by 31% (RR = 0.69; 95% CI = 0.56 to 0.86) and mortality was reduced by 38% (RR = 0.62; 95% CI = 0.40 to 0.96) compared with the control group. A single flexible sigmoidoscopy screening between ages 55 and 64 years was associated with a substantial reduction of CRC incidence and mortality.

Is sibling rivalry fatal?: siblings and mortality clustering.

PubMed

Kippen, Rebecca; Walters, Sarah

2012-01-01

Evidence drawn from nineteenth-century Belgian population registers shows that the presence of similarly aged siblings competing for resources within a household increases the probability of death for children younger than five, even when controlling for the preceding birth interval and multiple births. Furthermore, in this period of Belgian history, such mortality tended to cluster in certain families. The findings suggest the importance of segmenting the mortality of siblings younger than five by age group, of considering the presence of siblings as a time-varying covariate, and of factoring mortality clustering into analyses.

The changing age distribution of prostate cancer in Canada.

2007-01-01

Prostate cancer incidence rates are still increasing steadily; mortality rates are levelling, possibly decreasing; and hospitalization rates for many diagnoses are decreasing. Our objective is to examine changes in age distributions of prostate cancer during these times of change. Prostate cancer cases were derived from the Canadian Cancer Registry, prostate cancer deaths from Vital Statistics, hospitalizations from the Hospital Morbidity File. Age-standardized rates were calculated based on the 1991 Canadian population. A prevalence correction for incidence rates was calculated. Age-specific incidence rates increased until 1995 for all ages, but a superimposed peak (1991-94) was greatest between ages 60-79. After 1995, increases in incidence continued for the under-70 age groups. Prevalence correction indicated the greatest underestimation of incidence rates for the oldest ages, but was less in Canada than in the United States. Mortality rates increased until 1994, then levelled and slowly decreased; age-specific mortality rates showed the greatest increase for the oldest ages but the earliest downturn for younger age groups. While hospitalizations dropped drastically after 1991, this drop was confined to elderly men (70+). Dramatic changes in age distributions of prostate cancer incidence, mortality and hospitalizations altered age profiles of men with prostate cancer. This illustrated the changing nature of prostate cancer as a public health issue and has important implications for health care provision, e.g., the increased numbers of younger new patients have different needs from the increasing numbers of elderly long-term patients who now spend less time in hospital.

Guillain-Barré syndrome (GBS) is a rare disease that consists of a group of neuropathic conditions. Very few epidemiological studies of GBS have been carried out in Spain. The aim of this study was to determine the trends in GBS mortality in the total population of Spain for the period 1999 to 2013. Data on GBS deaths were drawn from the National Statistics Institute of Spain. Crude and overall age-standardised GBS mortality rates were calculated and joinpoint regression models were used to describe trend changes. Mean age of deceased by GBS each year was also assessed. The overall age-standardised GBS mortality rate was 0.71 per million in 1999 and 0.40 in 2013. It was higher in men, 1.08 vs. 0.42 in 1999 and 0.48 vs. 0.35 in 2013. There was a statistically significant decrease in mortality during the study period. All the age-standardised mortality rates decreased (overall and by gender) from 1999 to 2013. The mean age at death increased with time, from 73 years in 1999 to 77 years in 2013. GBS mortality has improved in Spain during the last 15 years. The age of death has risen and the mortality rate has decreased.

To determine the relation between rehabilitation intensity and poststroke mortality. Retrospective cohort study. Nationwide claims data. From Taiwan's National Health Insurance claims databases, patients (N=6737; mean age, 66.9y; 40.3% women) hospitalized between 2001 and 2013 for a first-ever stroke who had mild to moderate stroke and survived the first 90 days of stroke were enrolled. The intensity of rehabilitation therapy within 90 days after stroke was categorized into low, medium, or high based on the tertile distribution of the number of rehabilitation sessions. Long-term all-cause mortality. The Cox proportional hazard models with Bonferroni correction were used to assess the association between rehabilitation intensity and mortality, adjusting for age, comorbidities, stroke severity, and other covariates. Patients in the high-intensity group were younger but had a higher burden of comorbidities and greater stroke severity. During follow-up, the high-intensity group was associated with a significantly lower adjusted risk (hazard ratio [HR], .73; 95% confidence interval [CI], .63-.84) of mortality than the low-intensity group, whereas the medium-intensity group carried a similar risk of mortality (HR, 0.94; 95% CI, 0.84-1.06) compared with the low-intensity group. This association was not modified by stroke severity. Among patients with mild to moderate stroke severity, high-intensity rehabilitation therapy within the first 90 days was associated with a lower mortality risk than low-intensity therapy. Efforts to promote high-intensity rehabilitation therapy for this group of patients with stroke should be encouraged. Copyright © 2017 American Congress of Rehabilitation Medicine.

To compare all-cause and cause-specific mortality among 3 distinct groups: within-country, rural-to-urban migrants, and rural and urban dwellers in a longitudinal cohort in Peru. The PERU MIGRANT Study, a longitudinal cohort study, used an age-stratified and sex-stratified random sample of urban dwellers in a shanty town community in the capital city of Peru, rural dwellers in the Andes, and migrants from the Andes to the shanty town community. Participants underwent a questionnaire and anthropomorphic measurements at a baseline evaluation in 2007-2008 and at a follow-up visit in 2012-2013. Mortality was determined by death certificate or family interview. Of the 989 participants evaluated at baseline, 928 (94%) were evaluated at follow-up (mean age 48 years; 53% female). The mean follow-up time was 5.1 years, totalling 4732.8 person-years. In a multivariable survival model, and relative to urban dwellers, migrant participants had lower all cause mortality (HR=0.30; 95% CI 0.12-0.78), and both the migrant (HR=0.07; 95% CI 0.01-0.41) and rural (HR=0.06; 95% CI 0.01-0.62) groups had lower cardiovascular mortality. Cardiovascular mortality of migrants remains similar to that of the rural group, suggesting that rural-to-urban migrants do not appear to catch up with urban mortality in spite of having a more urban cardiovascular risk factor profile.

Objectives To examine associations between sarcopenia, obesity, and sarcopenic obesity and risk of cardiovascular disease (CVD) and all-cause mortality in older men. Design Prospective cohort study. Setting British Regional Heart Study. Participants Men aged 60–79 years (n = 4,252). Measurements Baseline waist circumference (WC) and midarm muscle circumference (MAMC) measurements were used to classify participants into four groups: sarcopenic, obese, sarcopenic obese, or optimal WC and MAMC. The cohort was followed for a mean of 11.3 years for CVD and all-cause mortality. Cox regression analyses assessed associations between sarcopenic obesity groups and all-cause mortality, CVD mortality, CVD events, and coronary heart disease (CHD) events. Results There were 1,314 deaths, 518 CVD deaths, 852 CVD events, and 458 CHD events during follow-up. All-cause mortality risk was significantly greater in sarcopenic (HR = 1.41, 95% CI = 1.22–1.63) and obese (HR = 1.21, 95% CI = 1.03–1.42) men than in the optimal reference group, with the highest risk in sarcopenic obese (HR = 1.72, 95% CI = 1.35–2.18), after adjustment for lifestyle characteristics. Risk of CVD mortality was significantly greater in sarcopenic and obese but not sarcopenic obese men. No association was seen between sarcopenic obesity groups and CHD or CVD events. Conclusion Sarcopenia and central adiposity were associated with greater cardiovascular mortality and all-cause mortality. Sarcopenic obese men had the highest risk of all-cause mortality but not CVD mortality. Efforts to promote healthy aging should focus on preventing obesity and maintaining muscle mass. PMID:24428349

With the objective of describing mortality from traffic accidents in Bayamo, Cuba, in 2011 a review was performed of injured and deceased patients due to traffic accidents, recorded in the Hospital Carlos M. de Céspedes. Of the 1,365 injured patients treated in the emergency room, the predominant groups were individuals aged 25 to 44 years comprising 372 patients (27.3%) and men comprising 1,071 (78.5%). 46 people died, most from the same age group and male. Multiple traumatisms (52.6%) and craniofacial trauma (34.2%) were the predominant injuries. Motor vehicle-pedestrian accidents stood out with a mortality of 26.3%. In conclusion, mortality from traffic accidents predominately occurs in young male adults, whose fatal consequences are due to multiple traumatisms from road accidents.

The author investigates reasons for the low numbers of the Catalan population aged 16-25 in the early nineteenth century in Spain. Hypotheses considered include mass emigration of youth in that age group; extraordinarily high mortality during the period of the Napoleonic wars; immigration of persons aged over 25; and a decline in births during the period 1832-1841.

It is unclear whether age-related increases in N-terminal pro-brain natriuretic peptide (NT-proBNP) represent a normal physiological process-possibly affecting the prognostic power-of NT-proBNP-or reflect age-related subclinical pathological changes. To determine the effect of age on the short-term prognostic value of NT-proBNP in patients with chronic heart failure (CHF). Prospective observational study with inclusion and matching of consecutive patients aged >65 years (mean (SD) 73.1 (6.0) years) to patients <65 years (53.7 (8.6) years) with respect to NT-proBNP, New York Heart Association stage, sex and aetiology of CHF (final n = 443). University hospital outpatient departments in the UK and Germany. Chronic stable heart failure due to systolic left ventricular dysfunction. None. All-cause mortality. In both age groups, NT-proBNP was a significant univariate predictor of mortality, and independent of age, sex and other established risk markers. The prognostic information given by NT-proBNP was comparable between the two groups, as reflected by the 1-year mortality of 9% in both groups. The prognostic accuracy of NT-proBNP as judged by the area under the receiver operating characteristics curve for the prediction of 1-year mortality was comparable for elderly and younger patients (0.67 vs 0.71; p = 0.09). NT-proBNP reflects disease severity in elderly and younger patients alike. In patients with chronic stable heart failure, the NT-proBNP value carries the same 1-year prognostic information regardless of the age of the patient.

Many studies have investigated the effects of air pollutants on disease and mortality. However, the results remain inconsistent and inconclusive. We thought that the impact of different seasons or ages of people may explain these differences. Measurement of the five pollutants (particulate matter <10 microm in aerodynamic diameter (PM(10)), SO(2), NO(2), O(3), and CO) was monitored by automated measuring units at five different stations. Monitoring stations were provided by the Taiwan Environmental Protection Agency (EPA) from 1997 to 1999. The subjects in the study were classified in two groups: those 65 years of age and older, and those of all ages (including the subjects in the > or =65 group). Data on daily mortality caused by respiratory disease, cardiovascular disease, and all other causes including the two aforementioned was collected by the Taiwan Department of Health (DOH). A time-series regression model was used to analyze the relative risk of respiratory and cardiovascular diseases due to air pollution in the summer and winter seasons. Risk of death from all causes and mortality from cardiovascular diseases during winter was significantly positively correlated with levels of SO(2), CO, and NO(2) for both groups of subjects and additionally with PM(10) for the elderly (> or =65 years old) group. There were significant positive correlations with respiratory diseases and levels of O(3) for both groups. However, the only significant positive correlation was with O(3) (RR=1.283) for the elderly group during summer. No other parameters showed significance for either group. Our findings contribute to the evidence of an association between SO(2), CO, NO(2), and PM(10) and mortality from respiratory and cardiovascular diseases, especially among elderly people during the winter season.

Motor neuron disease mortality and lifetime petrol lead exposure: Evidence from national age-specific and state-level age-standardized death rates in Australia.

The age standardized death rate from motor neuron disease (MND) for persons 40-84 years of age in the Australian States of New South Wales, Victoria, and Queensland increased dramatically from 1958 to 2013. Nationally, age-specific MND death rates also increased over this time period, but the rate of the rise varied considerably by age-group. The historic use of lead (Pb) additives in Australian petrol is a candidate explanation for these trends in MND mortality (International Classification of Disease (ICD)-10 G12.2). Leveraging temporal and spatial variation in petrol lead exposure risk resulting from the slow rise and rapid phase-out of lead as a constituent in gasoline in Australia, we analyze relationships between (1) national age-specific MND death rates in Australia and age-specific lifetime petrol lead exposure, (2) annual between-age dispersions in age-specific MND death rates and age-specific lifetime petrol lead exposure; and (3) state-level age-standardized MND death rates as a function of age-weighted lifetime petrol lead exposure. Other things held equal, we find that a one percent increase in lifetime petrol lead exposure increases the MND death rate by about one-third of one percent in both national age-specific and state-level age-standardized models of MND mortality. Lending support to the supposition that lead exposure is a driver of MND mortality risk, we find that the annual between-age group standard deviation in age-specific MND death rates is strongly correlated with the between-age standard deviation in age-specific lifetime petrol lead exposure. Legacy petrol lead emissions are associated with age-specific MND death rates as well as state-level age-standardized MND death rates in Australia. Results indicate that we are approaching peak lead exposure-attributable MND mortality. Copyright © 2016 Elsevier Inc. All rights reserved.

The United Nations Sustainable Development Goal for health (SDG3) poses complex challenges for signatory countries that will require clear roadmaps to set priorities over the next 15 years. Building upon the work of the Commission on Investing in Health and published estimates of feasible global mortality SDG3 targets, we analysed Mexico's mortality to assess the feasibility of reducing premature (0-69 years) mortality and propose a path to meet SDG3. We developed a baseline scenario applying 2010 age-specific and cause-specific mortality rates from the Mexican National Institute of Statistics and Geography (INEGI) to the 2030 UN Population Division (UNPD) population projections. In a second scenario, INEGI age-specific and cause-specific trends in death rates from 2000 to 2014 were projected to 2030 and adjusted to match the UNPD 2030 mortality projections. A third scenario assumed a 40% reduction in premature deaths across all ages and causes. By comparing these scenarios we quantified shortfalls in mortality reductions by age group and cause, and forecasted life expectancy pathways for Mexico to converge to better performing countries. UNPD-projected death rates yield a 25·9% reduction of premature mortality for Mexico. Accelerated reductions in adult mortality are necessary to reach a 40% reduction by 2030. Mortality declines aggregated across all age groups mask uneven gains across health disorders. Injuries, particularly road traffic accidents and homicides, are the main health challenge for young adults (aged 20-49 years) whereas unabated diabetes mortality is the single most important health concern for older adults (aged 50-69 years). Urgent action is now required to control non-communicable diseases and reduce fatal injuries in Mexico, making a 40% reduction in premature mortality by 2030 feasible and putting Mexico back on a track of substantial life expectancy convergence with better performing countries. Our study provides a roadmap for setting national health priorities. Further analysis of the equity implications of following the suggested pathway remains a subject of future research.

We hypothesized that in the very elderly dialysis patients in the United States, institutionalization in nursing homes would increase mortality in addition to age alone. Incident dialysis patients from 2001 to 2008 above the age of 70 were included. Patients above 70 were categorized into 4 groups according to age as 70-75, 76-80, 81-85, and >85 years and further divided into institutionalized and noninstitutionalized. Kaplan-Meier survival curves were plotted to assess patient survival. A total of 349,440 patients were identified above the age of 70 at the time of initiation of dialysis. For institutionalized patients, the mean survival was significantly lower, 1.71 ± 0.03 years for those in the age range 70-75, 1.44 ± 0.02 years for those in the age range 76-80, 1.25 ± 0.02 years for those in the age range 81-85, and 1.04 ± 0.02 for those in the >85 years age group (p = 0.0001). The hazard ratio for mortality in institutionalized elderly patients on dialysis was 1.80 ([95% CI 1.77-1.83]; p = 0.0001). After adjustment for other variables (multivariate Cox regression), to be institutionalized was still an independent risk factor for mortality (adjusted hazard ratio = 1.57 [95% CI 1.54-1.60]; p = 0.0001). There was increased mortality in institutionalized elderly patients as compared to noninstutionalized elderly patients in the same age group. In accordance with the increased frailty and decreased benefits of therapies in the very elderly, especially in those with additional co-morbidities besides age, palliative and end-of-life care should be considered. © 2017 S.

Background Ambient temperatures can cause an increase in mortality. A better understanding is needed of how health status and other factors modify the risk associated with high and low temperatures, to improve the basis of preventive measures. Differences in susceptibility to temperature and to heat and cold wave duration are relatively unexplored. Objectives We studied the associations between mortality and temperature and heat and cold wave duration, stratified by age and individual and medical factors. Methods Deaths among all residents of Stockholm County between 1990 and 2002 were linked to discharge diagnosis data from hospital admissions, and associations were examined using the time stratified case-crossover design. Analyses were stratified by gender, age, pre-existing disease, country of origin, and municipality level wealth, and adjusted for potential confounding factors. Results The effect on mortality by heat wave duration was higher for lower ages, in areas with lower wealth, for hospitalized patients younger than age 65. Odds were elevated among females younger than age 65, in groups with a previous hospital admission for mental disorders, and in persons with previous cardiovascular disease. Gradual increases in summer temperatures were associated with mortality in people older than 80 years, and with mortality in groups with a previous myocardial infarction and with chronic obstructive pulmonary disease (COPD) in the population younger than 65 years. During winter, mortality was associated with a decrease in temperature particularly in men and with the duration of cold spells for the population older than 80. A history of hospitalization for myocardial infarction increased the odds associated with cold temperatures among the population older than 65. Previous mental disease or substance abuse increased the odds of death among the population younger than 65. Conclusion To increase effectiveness, we suggest preventive efforts should not assume susceptible groups are the same for warm and cold days and heat and cold waves, respectively. PMID:24647126

To compare effect of placental transfusion by delayed cord clamping (DCC) or cord milking (CM) with early cord clamping (ECC) on a composite of mortality or abnormal neurological status at 40 weeks' post-menstrual age (PMA) and 24-30 months' chronological age in neonates of 30-33 weeks' gestation. Randomized, controlled trial. A composite of mortality or abnormal neurological status at 40 weeks PMA and survival free of neurodevelopmental abnormalities at 24-30 months' chronological age. A total of 461 neonates were randomized to placental transfusion (n = 233) or to ECC (n = 228). Among those assigned to placental transfusion group, 173 underwent DCC while in the remaining 60, CM was done. Incidence of mortality or abnormal neurological status at 40 weeks PMA (43 (18%) vs 35 (15%), RR (95% CI) 1.2 (0.8, 1.8), p = 0.4) and survival free of neurodevelopmental impairment at 24-30 months of chronological age (99 (47%) vs. 100 (50%); RR (95% CI): 0.9 (0.8, 1.2); P = 0.9) was similar between the study groups. The placental transfusion group showed a trend towards lower incidence of necrotizing enterocolitis. In 30-33 weeks' gestation preterm neonates, placental transfusion as compared to early cord clamping resulted in similar mortality or abnormal neurological status at 40 weeks PMA and at 24-30 months of chronological age.

This retrospective, population-based study investigated the patterns and risks of mortality from breast cancer, other cancers and non-cancer causes according to the age at diagnosis of breast cancer. Mortality was assessed in all Australian women (n = 179,653) aged 30-79 years who were diagnosed with breast cancer between 1982 and 2004 and who survived a minimum of 1 year. The mean follow up was 6.3 years (range 0-23 years). Before December 2005, 52,934 women had died (34,459 of breast cancer, 5019 of other cancers and 13,456 of non-cancer causes). There was an inverse age-related relative risk of mortality (calculated as the standardized mortality ratio [SMR]) from breast cancer (linear trend across age P < 0.01). For breast cancer survivors the age-adjusted SMR was 0.99 for other cancers and 0.81(P < 0.01) for non-cancer causes in comparison with the general population. The SMR for other cancers and non-cancer causes was highest in the 30-39-year-old age group (2.13, P < 0.01 and 2.15, P < 0.01, respectively), and progressively decreased with increasing age, with the 70-79-year-old age group having significantly reduced SMR (0.95, P < 0.05, and 0.78, P < 0.01, respectively, compared with the age-matched general population). There was an inverse age-related relative risk of death from breast cancer, other cancers and non-cancer causes. These findings suggest that younger Australian women require long-term health surveillance and that older women with limited comorbidities require optimal treatment of their breast cancer. © 2012 Wiley Publishing Asia Pty Ltd.

Perforated peptic ulcer disease continues to inflict high morbidity and mortality. Although patients can be stratified according to their surgical risk, optimal management has yet to be described. In this study we demonstrate a treatment option that improves the mortality among critically ill, poor risk patients with perforated peptic ulcer disease. In our study, two series were retrospectively reviewed: group A patients (n = 522) were treated in a single surgical unit at the Dhaka Medical College Hospital, Dhaka, Bangladesh during the 1980s. Among them, 124 patients were stratified as poor risk based on age, delayed presentation, peritoneal contamination, and coexisting medical problems. These criteria were the basis for selecting a group of poor risk patients (n = 84) for minimal surgical intervention (percutaneous peritoneal drainage) out of a larger group of patients, group B (n = 785) treated at Khulna Medical College Hospital during the 1990s. In group A, 479 patients underwent conventional operative management with an operative mortality of 8.97%. Among the 43 deaths, 24 patients were >60 years of age (55.8%), 12 patients had delayed presentation (27.9%), and 7 patients were in shock or had multiple coexisting medical problems (16.2%). In group B, 626 underwent conventional operative management, with 26 deaths at a mortality rate of 4.15%. Altogether, 84 patients were stratified as poor risk and were managed with minimal surgical intervention (percutaneous peritoneal drainage) followed by conservative treatment. Three of these patients died with an operative mortality of 3.5%. Minimal surgical intervention (percutaneous peritoneal drainage) can significantly lower the mortality rate among a selected group of critically ill, poor risk patients with perforated peptic ulcer disease.

Socioeconomic Disparities in Alcohol-Related Mortality in Sweden, 1991-2006: A Register-Based Follow-Up Study.

To examine whether apparent stability of overall alcohol-related mortality in Sweden during a period when traditionally strict alcohol policies went through a series of liberalizations and overall alcohol mortality remained stable, concealed a heterogeneity across socioeconomic groups (defined by educational level); and whether an increase occurred in the contribution of alcohol-related mortality to overall mortality differentials. Drawing on cause of death data linked to census records for the period 1991-2006, we computed annual age-standardized and sex-specific rates of alcohol-related mortality for groups with low, intermediate and high education. Alcohol-related mortality was considerably higher in lower educational groups for both men and women. For men, the trends in alcohol-related mortality were roughly stable for all education groups, and there were no signs of increasing inequalities by education. For women, alcohol-related mortality increased significantly for the low-education group whereas the two higher education groups showed no significant time trends, thus resulting in a widened educational gap in alcohol mortality for women. Alcohol's contribution to the overall mortality differentials declined for men and was basically unchanged for women. The findings provide only partial support to the hypothesis that the liberalizations of Swedish alcohol policy have been followed by a general increase in socioeconomic disparities in alcohol-related mortality. © The Author 2015.

OBJECTIVES Aortic root surgery is transitioning to aortic valve sparing (AVS), but little is known about the relative early outcomes of AVS versus composite graft-valve replacement (CVR). This study assessed mortality differences for AVS versus CVR to guide future practice decisions. METHODS From January 2000 to June 2011, 31 747 patients had aortic root replacement with AVS (n = 3585; 11%) or CVR (n = 28 162; 89%). The cohort of Overall patients was divided into two subgroups: high-risk patients (n = 20 356; 6% AVS) having age >75 years, endocarditis, aortic stenosis, dialysis, multiple valves, reoperation or emergency/salvage status, and the remaining low-risk patients (n = 11 388; 21% AVS). Using logistic regression analysis, outcomes were presented as unadjusted operative mortality (UOM), risk-adjusted operative mortality (AOM) and adjusted odds ratio (AOR) for mortality. RESULTS Baseline characteristics for the Overall group (AVS versus CVR) were: mean age (52 vs 57 years), endocarditis (1 vs 11%), aortic stenosis (4 vs 36%), dialysis (1 vs 2%), multiple valves (7 vs 10%), reoperation (6 vs 17%) and emergency status (14 vs 12%) (all P < 0.0001). In high- and low-risk groups, baseline differences narrowed, and lower mortality was generally observed with AVS: (AVS versus CVR) UOM group Overall (4.5 vs 8.9%)*, group High-risk (10.5 vs 11.7%), group Low-risk (1.4 vs 3.1%)*; AOM group Overall (6.2 vs 8.6%), group High-risk (10.1 vs 11.7%), group Low-risk (2.2 vs 2.8%); AOR group Overall (0.59)*, group High-risk (0.62)*, group Low-risk (0.69). *P < 0.05. CONCLUSIONS Relative risk-adjusted mortality seemed comparable with AVS versus CVR in low- and high-risk subgroups. These data support judicious expansion of aortic valve repair in patients having aortic root replacement. PMID:24639452

AIM To determine how statins, testosterone (T) replacement therapy (TRT) and phosphodiesterase 5-inhibitors (PDE5I) influence age related mortality in diabetic men. METHODS We studied 857 diabetic men screened for the BLAST study, stratifying them (mean follow-up = 3.8 years) into: (1) Normal T levels/untreated (total T > 12 nmol/L and free T > 0.25 nmol/L), Low T/untreated and Low T/treated; (2) PDE5I/untreated and PDE5I/treated; and (3) statin/untreated and statin/treated groups. The relationship between age and mortality, alone and with T/TRT, statin and PDE5I treatment was studied using logistic regression. Mortality probability and 95%CI were calculated from the above models for each individual. RESULTS Age was associated with mortality (logistic regression, OR = 1.10, 95%CI: 1.08-1.13, P < 0.001). With all factors included, age (OR = 1.08, 95%CI: 1.06-1.11, P < 0.001), Low T/treated (OR = 0.38, 95%CI: 0.15-0.92, P = 0.033), PDE5I/treated (OR = 0.17, 95%CI: 0.053-0.56, P = 0.004) and statin/treated (OR = 0.59, 95%CI: 0.36-0.97, P = 0.038) were associated with lower mortality. Age related mortality was as described by Gompertz, r2 = 0.881 when Ln (mortality) was plotted against age. The probability of mortality and 95%CI (from logistic regression) of individuals, treated/untreated with the drugs, alone and in combination was plotted against age. Overlap of 95%CI lines was evident with statins and TRT. No overlap was evident with PDE5I alone and with statins and TRT, this suggesting a change in the relationship between age and mortality. CONCLUSION We show that statins, PDE5I and TRT reduce mortality in diabetes. PDE5I, alone and with the other treatments significantly alter age related mortality in diabetic men. PMID:28344753

Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) estimated age-specific and sex-specific all-cause mortality between 1970 and 2016 for 195 countries and territories and at the subnational level for the five countries with a population greater than 200 million in 2016. We have evaluated how well civil registration systems captured deaths using a set of demographic methods called death distribution methods for adults and from consideration of survey and census data for children younger than 5 years. We generated an overall assessment of completeness of registration of deaths by dividing registered deaths in each location-year by our estimate of all-age deaths generated from our overall estimation process. For 163 locations, including subnational units in countries with a population greater than 200 million with complete vital registration (VR) systems, our estimates were largely driven by the observed data, with corrections for small fluctuations in numbers and estimation for recent years where there were lags in data reporting (lags were variable by location, generally between 1 year and 6 years). For other locations, we took advantage of different data sources available to measure under-5 mortality rates (U5MR) using complete birth histories, summary birth histories, and incomplete VR with adjustments; we measured adult mortality rate (the probability of death in individuals aged 15-60 years) using adjusted incomplete VR, sibling histories, and household death recall. We used the U5MR and adult mortality rate, together with crude death rate due to HIV in the GBD model life table system, to estimate age-specific and sex-specific death rates for each location-year. Using various international databases, we identified fatal discontinuities, which we defined as increases in the death rate of more than one death per million, resulting from conflict and terrorism, natural disasters, major transport or technological accidents, and a subset of epidemic infectious diseases; these were added to estimates in the relevant years. In 47 countries with an identified peak adult prevalence for HIV/AIDS of more than 0·5% and where VR systems were less than 65% complete, we informed our estimates of age-sex-specific mortality using the Estimation and Projection Package (EPP)-Spectrum model fitted to national HIV/AIDS prevalence surveys and antenatal clinic serosurveillance systems. We estimated stillbirths, early neonatal, late neonatal, and childhood mortality using both survey and VR data in spatiotemporal Gaussian process regression models. We estimated abridged life tables for all location-years using age-specific death rates. We grouped locations into development quintiles based on the Socio-demographic Index (SDI) and analysed mortality trends by quintile. Using spline regression, we estimated the expected mortality rate for each age-sex group as a function of SDI. We identified countries with higher life expectancy than expected by comparing observed life expectancy to anticipated life expectancy on the basis of development status alone. Completeness in the registration of deaths increased from 28% in 1970 to a peak of 45% in 2013; completeness was lower after 2013 because of lags in reporting. Total deaths in children younger than 5 years decreased from 1970 to 2016, and slower decreases occurred at ages 5-24 years. By contrast, numbers of adult deaths increased in each 5-year age bracket above the age of 25 years. The distribution of annualised rates of change in age-specific mortality rate differed over the period 2000 to 2016 compared with earlier decades: increasing annualised rates of change were less frequent, although rising annualised rates of change still occurred in some locations, particularly for adolescent and younger adult age groups. Rates of stillbirths and under-5 mortality both decreased globally from 1970. Evidence for global convergence of death rates was mixed; although the absolute difference between age-standardised death rates narrowed between countries at the lowest and highest levels of SDI, the ratio of these death rates-a measure of relative inequality-increased slightly. There was a strong shift between 1970 and 2016 toward higher life expectancy, most noticeably at higher levels of SDI. Among countries with populations greater than 1 million in 2016, life expectancy at birth was highest for women in Japan, at 86·9 years (95% UI 86·7-87·2), and for men in Singapore, at 81·3 years (78·8-83·7) in 2016. Male life expectancy was generally lower than female life expectancy between 1970 and 2016, and the gap between male and female life expectancy increased with progression to higher levels of SDI. Some countries with exceptional health performance in 1990 in terms of the difference in observed to expected life expectancy at birth had slower progress on the same measure in 2016. Globally, mortality rates have decreased across all age groups over the past five decades, with the largest improvements occurring among children younger than 5 years. However, at the national level, considerable heterogeneity remains in terms of both level and rate of changes in age-specific mortality; increases in mortality for certain age groups occurred in some locations. We found evidence that the absolute gap between countries in age-specific death rates has declined, although the relative gap for some age-sex groups increased. Countries that now lead in terms of having higher observed life expectancy than that expected on the basis of development alone, or locations that have either increased this advantage or rapidly decreased the deficit from expected levels, could provide insight into the means to accelerate progress in nations where progress has stalled.

Since the scientific revolution of the 18th century, human health has gradually improved, but there is no unifying theory that explains this improvement in health. Studies of macrodeterminants have produced conflicting results. Most studies have analysed health at a given point in time as the outcome; however, the rate of improvement in health might be a more appropriate outcome. Twenty-eight OECD member countries were selected for analysis in the period 1990-2010. The main outcomes studied, in six age groups, were the national rates of decrease in mortality in the period 1990-2010. The effects of seven potential determinants on the rates of decrease in mortality were analysed in linear multiple regression models using least squares, controlling for country-specific history constants, which represent the mortality rate in 1990. The multiple regression analyses started with models that only included mortality rates in 1990 as determinants. These models explained 87% of the intercountry variation in the children aged 1-4 years and 51% in adults aged 55-74 years. When added to the regression equations, the seven determinants did not seem to significantly increase the explanatory power of the equations. The analyses indicated a decrease in mortality in all nations and in all age groups. The development of mortality rates in the different nations demonstrated significant catch-up effects. Therefore an important objective of the national public health sector seems to be to reduce the delay between international research findings and the universal implementation of relevant innovations.

An increase in suicide mortality is often observed in economic recessions. The objective of this study was to analyse trends in socioeconomic inequalities in suicide mortality before and during the economic recession in two geographical settings in Spain. This study analyses inequalities in mortality according to educational level during 3 different time periods based on individual data from the Basque Country and Barcelona city. We analysed suicide mortality data for all residents over 25 years of age from 2001 to 2012. Two periods before the crisis (2001-2004 and 2005-2008) and another during the crisis (2009-2012) were studied. We performed independent analyses for sex, age group, and for the two geographical settings. We fit Poisson regression models to study the relationship between educational level and mortality, and calculated the relative index of inequality (RII) and the slope index of inequality (SII) as comparative measures. For men in the Basque Country, all RII values for the three time periods were similar and almost all were greater than 2; in Barcelona the RII values were generally lower. The SII values for Barcelona tended to decrease over time, whereas in the Basque Country they showed a U-shaped pattern. Among women aged 25-44 years we found an association between educational level and suicide mortality during the first time period; however, we found no clear association for other age groups or time periods. This study within two geographical settings in Spain shows that trends in inequalities in suicide mortality according to educational level remained stable among men before and during the economic recession.

Congenital malformations are a known cause of intrauterine death; of them, congenital heart diseases (CHDs) are accountable for the highest fetal and neonatal mortality rates. They are strongly associated with other extracardiac malformations and an early fetal mortality. Two hundred and twenty fves cases of CHDs are presented. Of them, 155 were isolated CHDs (group A) and 70 were associated with extracardiac malformations, chromosomal disorders, or genetic syndromes (group B). The overall mortality in group B was higher than that observed in group A (p <0.01). Prenatal mortality was similar in both groups: A: 8.4% (13 out of 155); B: 15.7% (11 out of 70). Postnatal mortality was A: 16.8% (26 out of 155) (p <0.01), OR: 0.52 (95% CI: 0.16-1.7); B: 32.9% (23 out of 70) (p <0.01), OR: 0.41 (95% CI: 0.20-0.83). Heart diseases associated with extracardiac abnormalities had a higher mortality rate than isolated congenital heart diseases in the period up to 60 weeks of postmenstrual age (140 days post-term). No differences were observed between both groups of patients in terms of prenatal mortality.

We examined long-term patterns of stressful life events (SLE) and their impact on mortality contrasting two theoretical models: allostatic load (linear relationship) and hormesis (inverted U relationship) in 1443 NAS men (aged 41–87 in 1985; M = 60.30, SD = 7.3) with at least two reports of SLEs over 18 years (total observations = 7,634). Using a zero-inflated Poisson growth mixture model, we identified four patterns of SLE trajectories, three showing linear decreases over time with low, medium, and high intercepts, respectively, and one an inverted U, peaking at age 70. Repeating the analysis omitting two health-related SLEs yielded only the first three linear patterns. Compared to the low-stress group, both the moderate and the high-stress groups showed excess mortality, controlling for demographics and health behavior habits, HRs = 1.42 and 1.37, ps <.01 and <.05. The relationship between stress trajectories and mortality was complex and not easily explained by either theoretical model. PMID:21961066

This paper analyses the relationship between extreme temperatures and mortality among persons aged 45-64 years. Daily mortality in Madrid was analysed by sex and cause, from January 1986 to December 1997. Quantitative analyses were performed using generalised additive models, with other covariables, such as influenza, air pollution and seasonality, included as controls. Our results showed that impact on mortality was limited for temperatures ranging from the 5th to the 95th percentiles, and increased sharply thereafter. During the summer period, the effect of heat was detected solely among males in the target age group, with an attributable risk (AR) of 13.3% for circulatory causes. Similarly, NO(2) concentrations registered the main statistically significant associations in females, with an AR of 15% when circulatory causes were considered. During winter, the impact of cold was exclusively observed among females having an AR of 7.7%. The magnitude of the AR indicates that the impact of extreme temperature is by no means negligible.

Various viruses are known to be associated with pneumonia. However, the impact of viral infections on adult pneumonia mortality remains unclear. This study aimed to clarify the effect of virus infection on pneumonia mortality among adults stratified by virus type and patient comorbidities. This multicentre prospective study enrolled pneumonia patients aged ≥15 years from September 2011 to August 2014. Sputum samples were tested by in-house multiplex polymerase chain reaction assays to identify 13 respiratory viruses. Viral infection status and its effect on in-hospital mortality were examined by age group and comorbidity status. A total of 2617 patients were enrolled in the study and 77.8% was aged ≥65 years. 574 (21.9%) did not have comorbidities, 790 (30.2%) had chronic respiratory disease, and 1253 (47.9%) had other comorbidities. Viruses were detected in 605 (23.1%) patients. Human rhinovirus (9.8%) was the most frequently identified virus, followed by influenza A (3.9%) and respiratory syncytial virus (3.9%). Respiratory syncytial virus was more frequently identified in patients with chronic respiratory disease (4.7%) than those with other comorbidities (4.2%) and without comorbidities (2.1%) (p = 0.037). The frequencies of other viruses were almost identical between the three groups. Virus detection overall was not associated with increased mortality (adjusted risk ratio (ARR) 0.76, 95% CI 0.53-1.09). However, influenza virus A and B were associated with three-fold higher mortality in patients with chronic respiratory disease but not with other comorbidities (ARR 3.38, 95% CI 1.54-7.42). Intriguingly, paramyxoviruses were associated with dramatically lower mortality in patients with other comorbidities (ARR 0.10, 95% CI 0.01-0.70) but not with chronic respiratory disease. These effects were not affected by age group. The impact of virus infections on pneumonia mortality varies by virus type and comorbidity status in adults.

We aimed to compare the efficacy of primary percutaneous coronary intervention (p-PCI) in patients >=80 versus <80 years of age with ST-segment elevation myocardial infarction (STEMI). We retrospectively enrolled 2213 patients with acute STEMI. The patients were prospectively followed up for a median of 42 months. Early and late clinical outcomes were compared according to age. One-hundred and seventy-nine (8.1%) of the 2213 patients were aged >=80 years. Post-procedural TIMI grade 3 flow was significantly less frequent in the age >=80 years patients (82.1% vs. 91.1%, p<0.001). Rates of mortality (14.5% vs. 3.4%, p<0.001), heart failure (20.7% vs. 10.5%, p<0.001), major hemorrhage (9.5% vs. 3.3%, p<0.001), secondary VT/VF (10.1% vs. 4.2%, p=0.002) and atrial fibrillation (12.8% vs. 4.3%, p<0.001) during the early hospitalization period were significantly higher in the age >=80 years patient group. Overall rates of mortality (40% vs. 9.7%, p<0.001) and total stroke (5.6% vs. 1.1%, p=0.005) at long-term follow-up were also higher in the age >=80 years patient group. However, there was no difference between the two groups with respect to the reinfarction/revascularization rates. Analysis, using the Cox proportional hazards model, revealed that age >=80 to was an independent predictor of long-term mortality (hazard ratio 2.17, 95% CI 1.23-4.17, p=0.02). Age is an independent predictor of mortality after p-PCI for STEMI. Although it seems to improve early outcomes, the efficacy of p-PCI at long-term follow-up is limited in elderly patients.

In recent decades, mortality rates for cerebrovascular diseases (CVD) have decreased significantly in many countries. This study analyses recent tendencies in CVD mortality rates in Andalusia (1980-2014) to identify any changes in previously observed sex and age trends. CVD mortality and population data were obtained from Spain's National Statistics Institute database. We calculated age-specific and age-standardised mortality rates using the direct method (European standard population). Joinpoint regression analysis was used to estimate the annual percentage change in rates and identify significant changes in mortality trends. We also estimated rate ratios between Andalusia and Spain. Standardised rates for both males and females showed 3 periods in joinpoint regression analysis: an initial period of significant decline (1980-1997), a period of rate stabilisation (1997-2003), and another period of significant decline (2003-2014). Between 1997 and 2003, age-standardised rates stabilised in Andalusia but continued to decrease in Spain as a whole. This increased in the gap between CVD mortality rates in Andalusia and Spain for both sexes and most age groups. Copyright © 2017 The Author(s). Publicado por Elsevier España, S.L.U.

To assess mortality and treatment costs of a new management protocol with preferential use of emergency endovascular aneurysm repair (eEVAR) for acute abdominal aortic aneurysm (AAA). From September 2003 until February 2005, 49 consecutive patients (45 men; mean age 71 years) with acute AAA were entered into a prospective study of a new management protocol that featured preferential use of eEVAR (n=18); patients with unsuitable anatomy or who were hemodynamically unstable underwent open repair (n=31). Mortality data and costs of treatment were compared in this mixed prospective group to a historical control group consisting of 147 patients (128 men; mean age 71 years) who underwent open repair from January 1998 to December 2001. All direct medical costs were included from the moment of admission until discharge from the hospital. Mortality in the mixed prospective group (18%) was lower than in the historical control group (31%), but the difference did not reach statistical significance (p=0.099). The mean total cost in the mixed prospective group was 17,164 euro compared to 21,084 euro in the historical open repair group (p=0.255). A preferential eEVAR protocol for acute AAA can decrease mortality and does not increase overall costs during initial treatment, but larger studies are needed to determine if these trends are statistically significant.

Liver Cancer has been a leading cause of death in Thailand. The purpose of this study was to model and forecast liver cancer mortality rate in Thailand using death certificate reports. A retrospective analysis of the liver cancer mortality rate was conducted. Numbering of 123,280 liver cancer causes of death cases were obtained from the national vital registration database for the 10-year period from 2000 to 2009, provided by the Ministry of Interior and coded as cause-of-death using ICD-10 by the Ministry of Public Health. Multivariate regression model was used for modeling and forecasting age-specific liver cancer mortality rates in Thailand. Liver cancer mortality increased with increasing age for each sex and was also higher in the North East provinces. The trends of liver cancer mortality remained stable in most age groups with increases during ten-year period (2000 to 2009) in the Northern and Southern. Liver cancer mortality was higher in males and increase with increasing age. There is need of liver cancer control measures to remain on a sustained and long-term basis for the high liver cancer burden rate of Thailand.

The Contribution of Smoking to Black-White Differences in U.S. Mortality

Smoking has significantly impacted American mortality and remains a major cause of morbidity and mortality. No previous study has systematically examined the contribution of smoking-attributable deaths to mortality trends among blacks or to black-white mortality differences at older ages over time in the United States. In this article, we employ multiple methods and data sources to provide a comprehensive assessment of this contribution. We find that smoking has contributed to the black-white gap in life expectancy at age 50 for males, accounting for 20 % to 48 % of the gap between 1980 and 2005, but not for females. The fraction of deaths attributable to smoking at ages above 50 is greater for black males than for white males; and among men, current smoking status explains about 20 % of the black excess relative risk in all-cause mortality at ages above 50 without adjustment for socioeconomic characteristics. These findings advance our understanding of the contribution of smoking to contemporary mortality trends and differences and reinforce the need for interventions that better address the needs of all groups.

Age-specific and sex-specific morbidity and mortality from avian influenza A(H7N9).

Dudley, Joseph P; Mackay, Ian M

We used data on age and sex for 136 laboratory confirmed human A(H7N9) cases reported as of 11 August 2013 to compare age-specific and sex-specific patterns of morbidity and mortality from the avian influenza A(H7N9) virus with those of the avian influenza A(H5N1) virus. Human A(H7N9) cases exhibit high degrees of age and sex bias: mortality is heavily biased toward males >50 years, no deaths have been reported among individuals <25 years old, and relatively few cases documented among children or adolescents. The proportion of fatal cases (PFC) for human A(H7N9) cases as of 11 August 2013 was 32%, compared to a cumulative PFC for A(H5N1) of 83% in Indonesia and 36% in Egypt. Approximately 75% of cases of all A(H7N9) cases occurred among individuals >45 years old. Morbidity and mortality from A(H7N9) are lowest among individuals between 10 and 29 years, the age group which exhibits the highest cumulative morbidity and case fatality rates from A(H5N1). Although individuals <20 years old comprise nearly 50% of all human A(H5N1) cases, only 7% of all reported A(H7N9) cases and no deaths have been reported among individuals in this age group. Only 4% of A(H7N9) cases occurred among children<5 years old, and only one case from the 10 to 20 year age group. Age- and sex-related differences in morbidity and mortality from emerging zoonotic diseases can provide insights into ecological, economic, and cultural factors that may contribute to the emergence and proliferation of novel zoonotic diseases in human populations.

Aim To determine biological (sex and age), socioeconomic (marital status, education, and mother tongue) and geographical (region) factors connected with causes of death and lifespan (age at death, years-of-potential-life-lost, and mortality rate) in Slovenia in the 1990s. Methods In this population-based cross-sectional study, we analyzed all deaths in the 25-64 age group (N = 14 816) in Slovenia in 1992, 1995, and 1998. Causes of death, classified into groups according to the 10th revision of International Classification of Diseases, were linked to the data on the deceased from the 1991 Census. Stratified contingency-table analyses were performed. Years-of-potential-life-lost (YPLL) were calculated on the basis of population life-tables stratified by region and linearly modeled by the characteristics of the deceased. Poisson regression was applied to test the differences in mortality rate. Results Across all socioeconomic strata, men died at younger age than women (index of excess mortality in men exceeded 200 for all studied years) and from different prevailing causes (injuries in men aged <45 years; neoplasms in women aged >35 years). For men, higher education was associated with fewer deaths from digestive and respiratory system diseases. The least educated women died relatively often from circulatory diseases, but rarely from neoplasms. Single people died from neoplasms less often. Marriage in comparison with divorce reduced the mortality rate by 1.9-fold in both men and women (P<0.001). Mortality rate in both men and women decreased with increasing education level (P<0.001). Mortality rate of ethnic Slovenians was half the mortality rate of ethnic minority members and immigrants (P<0.001). Analysis of YPLL revealed limited and nonlinear impact of education level on premature mortality. The share of neoplasms was the highest in the cluster of socioeconomically prosperous regions, whereas the share of circulatory diseases was increased in poorer regions. Significant differences were found between individual regions in age at death and mortality rate, and the differences decreased over the studied period. Conclusion These data may aid in understanding the nature, prevalence and consequences of mortality as related to socioeconomic inequalities, and thus serve as a basis for setting health and social policy goals and planning health measures.

Mortality and morbidity in the 21st century.

Case, Anne; Deaton, Angus

2017-01-01

We build on and extend the findings in Case and Deaton (2015) on increases in mortality and morbidity among white non-Hispanic Americans in midlife since the turn of the century. Increases in all-cause mortality continued unabated to 2015, with additional increases in drug overdoses, suicides, and alcohol-related liver mortality, particularly among those with a high-school degree or less. The decline in mortality from heart disease has slowed and, most recently, stopped, and this combined with the three other causes is responsible for the increase in all-cause mortality. Not only are educational differences in mortality among whites increasing, but from 1998 to 2015 mortality rose for those without, and fell for those with, a college degree. This is true for non-Hispanic white men and women in all five year age groups from 35-39 through 55-59. Mortality rates among blacks and Hispanics continued to fall; in 1999, the mortality rate of white non-Hispanics aged 50-54 with only a high-school degree was 30 percent lower than the mortality rate of blacks in the same age group but irrespective of education; by 2015, it was 30 percent higher . There are similar crossovers in all age groups from 25-29 to 60-64. Mortality rates in comparable rich countries have continued their pre-millennial fall at the rates that used to characterize the US. In contrast to the US, mortality rates in Europe are falling for those with low levels of educational attainment, and have fallen further over this period than mortality rates for those with higher levels of education. Many commentators have suggested that poor mortality outcomes can be attributed to contemporaneous levels of resources, particularly to slowly growing, stagnant, and even declining incomes; we evaluate this possibility, but find that it cannot provide a comprehensive explanation. In particular, the income profiles for blacks and Hispanics, whose mortality rates have fallen, are no better than those for whites. Nor is there any evidence in the European data that mortality trends match income trends, in spite of sharply different patterns of median income across countries after the Great Recession. We propose a preliminary but plausible story in which cumulative disadvantage from one birth cohort to the next, in the labor market, in marriage and child outcomes, and in health, is triggered by progressively worsening labor market opportunities at the time of entry for whites with low levels of education. This account, which fits much of the data, has the profoundly negative implication that policies, even ones that successfully improve earnings and jobs, or redistribute income, will take many years to reverse the mortality and morbidity increase, and that those in midlife now are likely to do much worse in old age than those currently older than 65. This is in contrast to an account in which resources affect health contemporaneously, so that those in midlife now can expect to do better in old age as they receive Social Security and Medicare. None of this implies that there are no policy levers to be pulled; preventing the over-prescription of opioids is an obvious target that would clearly be helpful.

Health care use by Medicare's disabled enrollees

Three million persons under age 65 are entitled to Medicare because of disability. This study examines their Medicare use and mortality. Disabled enrollees had higher health care use and mortality than comparison groups of Medicare's aged enrollees or of the general population under age 65. One type of disabled enrollee, adults disabled as children (over one-half of whom are mentally retarded) show lower use rates than the other types of enrollees—workers and widows. High mortality of the disabled during the 2-year waiting period for Medicare suggests the need to investigate how they pay for care during this period. PMID:10317775

Road accidents are a major public health problem that affect all age groups but their impact is most striking among the young. The aim of this study is to quantify the burden of road traffic injuries, their mortality and direct in-patient economic costs and to identify the age classes at highest risk for severe road traffic injuries, through analysis of data collected by information systems of an Italian Local Health Authority. The study was conducted in a Local Health Authority of Veneto Region. Injured people were selected from Emergency Department (2006-2010). Data were linked to the Hospital Information System for hospital admissions and to the Mortality Registry to check 30-day mortality. The direct costs associated to hospitalizations were estimated through Diagnosis Related Group reimbursement rates. Multivariate analysis was performed using hospitalization and mortality as the dependent variables and gender, age, day of week when accident occurred as the independent variables. Traffic injury, hospitalization and mortality incidence rates were calculated by gender and age per 100,000 residents per year. The road traffic injuries were 9,192, decreasing from 2,112 in 2006 to 1,980 in 2010. Among injured persons 55.3% were male (68.1% among 15-19 age class); 41.7% young people aged 15-34 years (43.9% among male, 39.0% among female). Total hospitalisation rate was 5.9%. Overall mortality rate was 0.3% (0.9% among aged 65 or older). The cost of hospital admission was euro 2,742,505 (hospitalization mean cost euro 5,097). Risk of hospitalization and death was higher in male, in elderly and during week end. Young people aged 15-19 had the highest incidence of visits (2,258.4 per 100,000) and high hospitalisation weekend and mortality rates (respectively 101.5 and 8.5). Analysis at local level, using current data sources, permits to estimate the burden of injuries caused by road-traffic, to describe the characteristics of injured persons and finally to estimate costs of care. All this information could be used to make the population aware of its own risk for road accidents. Linkage of these data with police and transport data is required to focus prevention on higher risk groups and to adopt effective local road safety strategies.

Objectives The main objective of this study was to explore differences in mortality patterns among two large immigrant groups in Germany: one from Turkey and the other from the former Soviet Union (FSU). To this end, we investigated indicators of premature mortality. Design This study was conducted as a retrospective population-based study based on mortality register linkage. Using mortality data for the period 2004–2010, we calculated age-standardised death rates (SDR) and standardised mortality ratios (SMR) for premature deaths (

We report here a historical cohort study on cancer mortality among Minamata disease (MD) patients (n = 1,351) in Kagoshima and Kumamoto Prefectures of Japan. Taking into account their living area, sex, age and fish eating habits, the residents (n = 5,667; 40 years of age or over at 1966) living in coastal areas of Kagoshima, who consumed fish daily, were selected as a reference group from the six-prefecture cohort study conducted by Hirayama et al. The observation periods of the MD patients and of the reference group were from 1973 to 1984 and from 1970 to 1981, respectively. Survival analysis using the Poisson regression model was applied for comparison of mortality between the MD patients and the reference group. No excess of relative risk (RR) adjusted for attained age, sex and follow-up period was observed for mortality from all causes, all cancers, and non-cancers combined. Analysis of site-specific cancers showed a statistically significant decrease in mortality from stomach cancer among MD patients (RR, 0.49; 95% confidence interval, 0.26-0.94). In addition, a statistically significant eight-fold excess risk, based on 5 observed deaths, was noted for mortality from leukemia (RR, 8.35; 95 % confidence interval 1.61-43.3). It is, however, unlikely for these observed risks to be derived from methylmercury exposure only. Further studies are needed to understand the mechanisms involved in the observed risks among MD patients.

Description of cervical cancer mortality in Belgium using Bayesian age-period-cohort models

PubMed Central

2009-01-01

Objective To correct cervical cancer mortality rates for death cause certification problems in Belgium and to describe the corrected trends (1954-1997) using Bayesian models. Method Cervical cancer (cervix uteri (CVX), corpus uteri (CRP), not otherwise specified (NOS) uterus cancer and other very rare uterus cancer (OTH) mortality data were extracted from the WHO mortality database together with population data for Belgium and the Netherlands. Different ICD (International Classification of Diseases) were used over time for death cause certification. In the Netherlands, the proportion of not-otherwise specified uterine cancer deaths was small over large periods and therefore internal reallocation could be used to estimate the corrected rates cervical cancer mortality. In Belgium, the proportion of improperly defined uterus deaths was high. Therefore, the age-specific proportions of uterus cancer deaths that are probably of cervical origin for the Netherlands was applied to Belgian uterus cancer deaths to estimate the corrected number of cervix cancer deaths (corCVX). A Bayesian loglinear Poisson-regression model was performed to disentangle the separate effects of age, period and cohort. Results The corrected age standardized mortality rate (ASMR) decreased regularly from 9.2/100 000 in the mid 1950s to 2.5/100,000 in the late 1990s. Inclusion of age, period and cohort into the models were required to obtain an adequate fit. Cervical cancer mortality increases with age, declines over calendar period and varied irregularly by cohort. Conclusion Mortality increased with ageing and declined over time in most age-groups, but varied irregularly by birth cohort. In global, with some discrete exceptions, mortality decreased for successive generations up to the cohorts born in the 1930s. This decline stopped for cohorts born in the 1940s and thereafter. For the youngest cohorts, even a tendency of increasing risk of dying from cervical cancer could be observed, reflecting increased exposure to risk factors. The fact that this increase was limited for the youngest cohorts could be explained as an effect of screening. Bayesian modeling provided similar results compared to previously used classical Poisson models. However, Bayesian models are more robust for estimating rates when data are sparse (youngest age groups, most recent cohorts) and can be used to for predicting future trends.

To assess whether joint pain or radiographic osteoarthritis (ROA) of the knee and hand is associated with all-cause and disease-specific mortality in middle-aged women. Four subgroups from the prospective community-based Chingford Cohort Study were identified based on presence/absence of pain and ROA at baseline: (Pain-/ROA-; Pain+/ROA-; Pain-/ROA+; Pain+/ROA+). Pain was defined as side-specific pain in the preceding month, while side-specific ROA was defined as Kellgren-Lawrence grade ≥2. All-cause, cardiovascular disease (CVD) and cancer-related mortality over the 23-year follow-up was based on information collected by the Office for National Statistics. Associations between subgroups and all-cause/cause-specific mortality were assessed using Cox regression, adjusting for age, body mass index, typical cardiovascular risk factors, occupation, past physical activity, existing CVD disease, glucose levels and medication use. 821 and 808 women were included for knee and hand analyses, respectively. Compared with the knee Pain-/ROA- group, the Pain+/ROA- group had an increased risk of CVD-specific mortality (HR 2.93 (95% CI 1.47 to 5.85)), while the knee Pain+/ROA+ group had an increased HR of 1.97 (95% CI 1.23 to 3.17) for all-cause and 3.57 (95% CI 1.53 to 8.34) for CVD-specific mortality. We found no association between hand OA and mortality. We found a significantly increased risk of all-cause and CVD-specific mortality in women experiencing knee pain with or without ROA but not ROA alone. No relationship was found between hand OA and mortality risk. This suggests that knee pain, more than structural changes of OA is the main driver of excess mortality in patients with OA.

Objectives We aimed to describe ethnic variations in infant mortality and explore the contribution of area deprivation, mother’s country of birth, and prematurity to these variations. Methods We analyzed routine birth and death data on singleton live births (gestational age≥22 weeks) in England and Wales, 2006–2012. Infant mortality by ethnic group was analyzed using logistic regression with adjustment for sociodemographic characteristics and gestational age. Results In the 4,634,932 births analyzed, crude infant mortality rates were higher in Pakistani, Black Caribbean, Black African, and Bangladeshi infants (6.92, 6.00, 5.17 and 4.40 per 1,000 live births, respectively vs. 2.87 in White British infants). Adjustment for maternal sociodemographic characteristics changed the results little. Further adjustment for gestational age strongly attenuated the risk in Black Caribbean (OR 1.02, 95% CI 0.89–1.17) and Black African infants (1.17, 1.06–1.29) but not in Pakistani (2.32, 2.15–2.50), Bangladeshi (1.47, 1.28–1.69), and Indian infants (1.24, 1.11–1.38). Ethnic variations in infant mortality differed significantly between term and preterm infants. At term, South Asian groups had higher risks which cannot be explained by sociodemographic characteristics. In preterm infants, adjustment for degree of prematurity (<28, 28–31, 32–33, 34–36 weeks) fully explained increased risks in Black but not Pakistani and Bangladeshi infants. Sensitivity analyses with further adjustment for small for gestational age, or excluding deaths due to congenital anomalies did not fully explain the excess risk in South Asian groups. Conclusions Higher infant mortality in South Asian and Black infants does not appear to be explained by sociodemographic characteristics. Higher proportions of very premature infants appear to explain increased risks in Black infants but not in South Asian groups. Strategies targeting the prevention and management of preterm birth in Black groups and suboptimal birthweight and modifiable risk factors for congenital anomalies in South Asian groups might help reduce ethnic inequalities in infant mortality.

Although bilateral internal mammary artery (BIMA) grafting is performed with increasing regularity in elderly patients, whether it is truly beneficial, and therefore indicated, in these patients remains uncertain. We retrospectively investigated early and late outcomes of BIMA grafting in patients aged ≥75 years. We identified 460 patients aged ≥75 years from among 2,618 patients who underwent either single internal mammary artery (SIMA) grafting (n=293) or BIMA grafting (n=107). Early outcomes did not differ between the SIMA and BIMA patients (30-day mortality: 1.7% vs. 0%, P=0.39; sternal wound infection: 1.0% vs. 4.7%; P=0.057). Late outcomes, 10-year survival in particular, were improved in the BIMA group (36.6% vs. 48.1%, P=0.033). In the analysis of the results in propensity score-matched groups (196 patients in the SIMA group, 98 patients in the BIMA group), improved 10-year survival was documented in the BIMA group (34.8% vs. 47.6%, P=0.030). Cox proportional regression analysis showed SIMA usage (non-use of BIMA) to be a predictor for late mortality (hazard ratio: 0.65, 95% confidence interval: 0.43-0.98, P=0.042). We further compared outcomes between the total non-elderly patients (n=2,158) and total elderly patients (n=460). BIMA usage was similar, as was 30-day mortality (1.0% vs. 1.3%, respectively). A survival advantage, with no increase in early mortality, can be expected from BIMA grafting in patients aged ≥75 years. (Circ J 2016; 80: 1756-1763).

Few studies have examined the health effects of employment situation among women, taking social and economic conditions into consideration. The objective of this research was to investigate the association of employment situation (full-time or part-time employee and self-employed) with mortality risk in women over a 20-year follow-up period. Additionally, we examined whether the association between employment situation and mortality in women differed by education level and marital status. We investigated the association of employment situation with mortality among 16,692 women aged 40-59 years enrolled in the Japan Collaborative Cohort Study. Multivariate HRs and 95% CIs for total deaths by employment situation were calculated after adjustment for age, disease history, residential area, education level, marital status and number of children. We also conducted subgroup analysis by education level and marital status. Multivariate HRs for mortality of part-time employees and self-employed workers were 1.48 (95% CI, 1.25 to 1.75) and 1.44 (95% CI, 1.21 to 1.72), respectively, with reference to women working full-time. Subgroup analysis by education level indicated that health effects in women according to employment situation were likely to be more evident in the low education-level group. Subgroup analysis by marital status indicated that this factor also affected the association between employment situation and risk of death. Among middle-aged Japanese women, employment situation was associated with mortality risk. Health effects were likely to differ by household structure and socioeconomic conditions.

Macroeconomic effects on mortality revealed by panel analysis with nonlinear trends.

PubMed

Ionides, Edward L; Wang, Zhen; Tapia Granados, José A

2013-10-03

Many investigations have used panel methods to study the relationships between fluctuations in economic activity and mortality. A broad consensus has emerged on the overall procyclical nature of mortality: perhaps counter-intuitively, mortality typically rises above its trend during expansions. This consensus has been tarnished by inconsistent reports on the specific age groups and mortality causes involved. We show that these inconsistencies result, in part, from the trend specifications used in previous panel models. Standard econometric panel analysis involves fitting regression models using ordinary least squares, employing standard errors which are robust to temporal autocorrelation. The model specifications include a fixed effect, and possibly a linear trend, for each time series in the panel. We propose alternative methodology based on nonlinear detrending. Applying our methodology on data for the 50 US states from 1980 to 2006, we obtain more precise and consistent results than previous studies. We find procyclical mortality in all age groups. We find clear procyclical mortality due to respiratory disease and traffic injuries. Predominantly procyclical cardiovascular disease mortality and countercyclical suicide are subject to substantial state-to-state variation. Neither cancer nor homicide have significant macroeconomic association.

The increased mortality in Poland compared to that observed just after the war was mainly caused by the elevated frequency of premature deaths (under 65 years of age). The aim of the work was to assess: the premature mortality in the population of the productive age in Poland in comparison with other countries of Central and Eastern Europe, Scandinavian and Western European countries as well as with other developed countries in the world; the dynamics of premature mortality; the spatial differentiation of premature mortality in our country. Two age phases: I = 20 - 44 years, and II = 45 - 64 years were identified in premature mortality. A considerable increase in male premature mortality in phase II of the productive age which began in the second half of the sixties and had continued until 1991 doubled the mortality ratio in Poland when compared with the average ratio observed in all Scandinavian and Western European countries. The analysis of spatial differentiation of premature mortality indicates clearly the relationship between mortality and environmental conditions: the highest ratios are noted in highly urbanized and industrialized voivodships (provinces). It accounts for possible reasons of shortened by 7-8 years period of men's life in Poland as compared to Western countries or even by 10 year in comparison with Japan, for example. The situation among women is more favorable. These alarming data on premature mortality, especially among men in phase II of the productive age emphasize the urgent need for in-depth studies of causes, circumstances and factors contributing to deaths at the most active productive age.

Background Breast cancer mortality has experienced important changes over the last century. Breast cancer occurs in the presence of other competing risks which can influence breast cancer incidence and mortality trends. The aim of the present work is: 1) to assess the impact of breast cancer deaths among mortality from all causes in Catalonia (Spain), by age and birth cohort and 2) to estimate the risk of death from other causes than breast cancer, one of the inputs needed to model breast cancer mortality reduction due to screening or therapeutic interventions. Methods The multi-decrement life table methodology was used. First, all-cause mortality probabilities were obtained by age and cohort. Then mortality probability for breast cancer was subtracted from the all-cause mortality probabilities to obtain cohort life tables for causes other than breast cancer. These life tables, on one hand, provide an estimate of the risk of dying from competing risks, and on the other hand, permit to assess the impact of breast cancer deaths on all-cause mortality using the ratio of the probability of death for causes other than breast cancer by the all-cause probability of death. Results There was an increasing impact of breast cancer on mortality in the first part of the 20th century, with a peak for cohorts born in 1945–54 in the 40–49 age groups (for which approximately 24% of mortality was due to breast cancer). Even though for cohorts born after 1955 there was only information for women under 50, it is also important to note that the impact of breast cancer on all-cause mortality decreased for those cohorts. Conclusion We have quantified the effect of removing breast cancer mortality in different age groups and birth cohorts. Our results are consistent with US findings. We also have obtained an estimate of the risk of dying from competing-causes mortality, which will be used in the assessment of the effect of mammography screening on breast cancer mortality in Catalonia.

Racial segregation, income inequality, and mortality in US metropolitan areas.

PubMed

Nuru-Jeter, Amani M; LaVeist, Thomas A

2011-04-01

Evidence of the association between income inequality and mortality has been mixed. Studies indicate that growing income inequalities reflect inequalities between, rather than within, racial groups. Racial segregation may play a role. We examine the role of racial segregation on the relationship between income inequality and mortality in a cross-section of US metropolitan areas. Metropolitan areas were included if they had a population of at least 100,000 and were at least 10% black (N = 107). Deaths for the time period 1991-1999 were used to calculate age-adjusted all-cause mortality rates for each metropolitan statistical area (MSA) using direct age-adjustment techniques. Multivariate least squares regression was used to examine associations for the total sample and for blacks and whites separately. Income inequality was associated with lower mortality rates among whites and higher mortality rates among blacks. There was a significant interaction between income inequality and racial segregation. A significant graded inverse income inequality/mortality association was found for MSAs with higher versus lower levels of black-white racial segregation. Effects were stronger among whites than among blacks. A positive income inequality/mortality association was found in MSAs with higher versus lower levels of Hispanic-white segregation. Uncertainty regarding the income inequality/mortality association found in previous studies may be related to the omission of important variables such as racial segregation that modify associations differently between groups. Research is needed to further elucidate the risk and protective effects of racial segregation across groups.

SUMMARY We examined mortality in early onset (age <12 months) epilepsy in a population-based group of children. Children with early onset epilepsy were significantly more likely to die (case fatality, CF 8/60 versus 8/407, p<0.001; mortality rate, MR 14.5/1000 versus 2/1000 person years; standardized mortality ratio, SMR 22.25 versus 5.67). Mortality was greater in children with malignant neonatal (age <1 month) epilepsy (CF 4/12 versus 12/450, p<0.001; MR 54/1000 person years versus 2.7/1000 person year; SMR 46.55 versus 7.22). Given that only 1/8 early onset epilepsy deaths was seizure-related, mortality appears to be more affected by underlying etiology. PMID:23582606

Colostomy creation is a common procedure performed in colon and rectal surgery. Outcomes by technique have not been well studied. This study evaluated outcomes related to open versus laparoscopic colostomy creation. This was a retrospective review of patients undergoing colostomy creation using univariate and multivariate propensity score analyses. Hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program database were included. Data on patients were obtained from the American College of Surgeons National Surgical Quality Improvement Program 2005-2011 Participant Use Data Files. We measured 30-day mortality, 30-day complications, and predictors of 30-day mortality. A total of 2179 subjects were in the open group and 1132 in the laparoscopic group. The open group had increased age (open, 64 years vs laparoscopic, 60 years), admission from facility (17.0% vs 14.9%), and disseminated cancer (26.1% vs 21.4%). All were statistically significant. The open group had a significantly higher percentage of emergency operations (24.9% vs 7.9%). Operative time was statistically different (81 vs 86 minutes). Thirty-day mortality was significantly higher in the open group (8.7% vs 3.5%), as was any 30-day complication (25.4% vs 17.0%). Propensity-matching analysis on elective patients only revealed that postoperative length of stay and rate of any wound complication were statistically higher in the open group. Multivariate analysis for mortality was performed on the full, elective, and propensity-matched cohorts; age >65 years and dependent functional status were associated with an increased risk of mortality in all of the models. This study has the potential for selection bias and limited generalizability. Colostomy creation at American College of Surgeons National Surgical Quality Improvement Program hospitals is more commonly performed open rather than laparoscopically. Patient age >65 years and dependent functional status are associated with an increased risk of 30-day mortality.

To determine the hospital outcomes of liveborn infants at 23-31 weeks following prelabour preterm rupture of membranes (PPROM). A regional retrospective cohort study of 4454 infants of 23-31 weeks' gestation admitted to a tertiary neonatal network between 2007 and 2011. Primary outcome was the composite chronic lung disease (CLD) or mortality at discharge. 225 (5%) neonates had a history of PPROM occurring prior to 24 +0 weeks (Early-PPROM), 829 (19%) had a history of PPROM at or after 24 +0 weeks' gestation (Late-PPROM) and 3400 (76%) had no history of PPROM (No-PPROM). In comparison to No-PPROM, Early-PPROM group had higher CLD/mortality in infants born at 23-27 weeks (OR 1.95; 95% CI 1.34 to 2.85) and 28-31 weeks (OR 4.98; 95% CI 2.99 to 8.28). Within Early-PPROM group, the latency of PPROM >14 days had lower CLD/mortality in comparison to latency ≤14 days (57.6% vs 77%, OR 0.40; 95% CI 0.21 to 0.76). Late-PPROM group had significantly lower CLD/mortality in comparison to No-PPROM group at 23-27 weeks (OR 0.50; 95% CI 0.37 to 0.69) and 28-31 weeks (OR 0.50; 95% CI 0.36 to 0.71). Within Late-PPROM group, latency >14 days was associated with an increased CLD/mortality in 28-31 weeks (14.1% vs 5.4%, OR 2.88; 95% CI 1.31 to 6.38). Early-PPROM prior to 24 weeks' gestation had high incidence of CLD/mortality even after correcting for gestational age. Late-PPROM at or after 24 weeks had lower CLD/mortality compared with No-PPROM. Latency >14 days in Late-PPROM group at 28-31 week group increased the odds of CLD/mortality.

OBJECTIVE: To analyze the characteristics of infant mortality at the extremes of maternal age. METHOD: Retrospective, cross-sectional quantitative study using data from Live Birth Certificates, Death Certificates and from Child Death Investigation records in Londrina, Paraná, in the years of 2000-2009. RESULTS: During the 10-year study period , there were 176 infant deaths among mothers up to 19 years of age, and 113 deaths among mothers aged 35 years or more. The infant mortality rate among young mothers was 14.4 deaths per thousand births, compared to 12.9 deaths in the other age group. For adolescent mothers, the following conditions prevailed: lack of a stable partner (p<0.001), lack of a paid job (p<0.001), late start of prenatal care in the second trimester of pregnancy (p<0.001), fewer prenatal visits (p<0.001) and urinary tract infections (p<0.001). On the other hand, women aged 35 or more had a higher occurrence of hypertension during pregnancy (p<0.001), and of surgical delivery (p<0.001). Regarding the underlying cause of infant death, congenital anomalies prevailed in the group of older mothers (p=0.002), and external causes were predominant in the group of young mothers (p=0.019). CONCLUSION: Both age groups deserve the attention of social services for maternal and child health, especially adolescent mothers, who presented a higher combination of factors deemed hazardous to the child's health.

2014-01-01

Physical inactivity is a major public health problem associated with increased mortality risk. It is, however, poorly understood whether vigorous physical activity is more beneficial for reducing mortality risk than activities of lower intensity. The aim of this study was to examine associations of the intensity and volume of leisure-time physical activity with all-cause mortality among middle-aged women and men while considering sociodemographic and health related factors as covariates. Questionnaire survey data collected in 2000-02 among 40-60-year-old employees of the City of Helsinki (N = 8960) were linked with register data on mortality (74% gave permission to the linkage) providing a mean follow-up time of 12-years. The analysis included 6429 respondents (79% women). The participants were classified into three groups according to intensity of physical activity: low moderate, high moderate and vigorous. The volume of physical activity was classified into three groups according to tertiles. Cox regression analysis was used to calculate hazard ratios (HR) and 95% confidence intervals (CIs) for all-cause mortality. During the follow up 205 participants died. Leisure-time physical activity was associated with reduced risk of mortality. After adjusting for covariates the vigorous group (HR = 0.54, 95% CI 0.34-0.86) showed a reduced risk of mortality compared with the low moderate group whereas for the high moderate group the reductions in mortality risk (HR = 0.72, 95% CI 0.48-1.08) were less clear. Adjusting for the volume of physical activity did not affect the point estimates. Higher volume of leisure-time physical activity was also associated with reduced mortality risk; however, adjusting for the covariates and the intensity of physical activity explained the differences. For healthy middle-aged women and men who engage in some physical activity vigorous exercise may provide further health benefits preventing premature deaths.

Traumatic brain injury (TBI) is an important health issue with high mortality. Various complications of physiological and cognitive impairment may result in disability or death after TBI. Grouping of these complications could be treated as integrated post-TBI syndromes. To improve risk estimation, grouping TBI complications should be investigated, to better predict TBI mortality. This study aimed to estimate mortality risk based on grouping of complications among TBI patients. Taiwan's National Health Insurance Research Database was used in this study. TBI was defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification codes: 801-804 and 850-854. The association rule data mining method was used to analyze coexisting complications after TBI. The mortality risk of post-TBI complication sets with the potential risk factors was estimated using Cox regression. A total 139,254 TBI patients were enrolled in this study. Intracerebral hemorrhage was the most common complication among TBI patients. After frequent item set mining, the most common post-TBI grouping of complications comprised pneumonia caused by acute respiratory failure (ARF) and urinary tract infection, with mortality risk 1.55 (95% C.I.: 1.51-1.60), compared with those without the selected combinations. TBI patients with the combined combinations have high mortality risk, especially those aged <20 years with septicemia, pneumonia, and ARF (HR: 4.95, 95% C.I.: 3.55-6.88). We used post-TBI complication sets to estimate mortality risk among TBI patients. According to the combinations determined by mining, especially the combination of septicemia with pneumonia and ARF, TBI patients have a 1.73-fold increased mortality risk, after controlling for potential demographic and clinical confounders. TBI patients aged<20 years with each combination of complications also have increased mortality risk. These results could provide physicians and caregivers with important information to increase their awareness about sequences of clinical syndromes among TBI patients, to prevent possible deaths among these patients.

Population groups living in deprived areas are more exposed to several risk factors for diseases and injuries and die prematurely when compared with their better-off counterparts. The strength and patterning of the relationships between socioeconomic status and mortality differ depending on age, gender, and diseases or injuries. The objective of this study was to identify the magnitude of social differences in mortality among adult residents in a city of one million people in Southeastern Brazil in 2004-2008. Forty-nine health care unit areas were classified into three homogeneous strata using 2000 Census small-area socioeconomic indicators. Mortality rates by age group, sex, and cause of death were calculated for each socioeconomic stratum. Mortality rate ratios (RR) and 95% confidence intervals were estimated for the low and middle socioeconomic strata compared with the high stratum. In general, age-specific mortality rates showed a social gradient of increasing risks of death with decreasing socioeconomic status. The highest mortality rate ratios between low and high strata were observed in the 30-39 age group for males (RR = 1.74, 95% CI 1.59-1.89), and females (RR = 1.90, 95% CI 1.65-2.15). Concerning specific diseases and injuries, the greatest inequalities between low and high strata were found for homicides (RR = 2.44, 95% CI 2.27-2.61) and traffic accidents (RR = 1.64, 95% CI 1.45-1.83) among males. For women, the highest inequalities between the low and high strata were for chronic respiratory diseases (RR = 2.19, 95% CI 1.94-2.45) and acute myocardial infarction (RR = 1.93, 95% CI 1.79-2.07). Only breast cancer showed a reversed social gradient (RR = 0.70, 95% CI 0.48-0.92). Inequalities in circulatory and respiratory diseases mortality were greater among females than among males. Substandard living conditions are related to unhealthy behaviors, as well as difficulties in accessing health care. Therefore, the Brazilian Health System (SUS) must ensure greater access to primary and hospital care, and develop programs that promote healthier lifestyles among vulnerable groups to reduce social inequalities in mortality. Moreover, because deaths from external causes are concentrated in poor areas, cooperative and coordinated intersectoral actions should be taken to combat the deadly violence cycle.

We carried out a cohort study of mortality among 954 Canadian military personnel exposed to low-dose ionizing radiation during nuclear reactor clean-up operations at Chalk River Nuclear Laboratories, Chalk River, Ont., and during observation of atomic test blasts in the United States and Australia in the 1950s. Two controls matched for age, service, rank and trade were selected for each exposed subject. Mortality among the exposed and control groups was ascertained by means of record linkage with the Canadian Mortality Data Base. Survival analysis with life-table techniques did not reveal any difference in overall mortality between the exposed and control groups. Analysis of cause-specific mortality showed similar mortality patterns in the two groups; there was no elevation in the exposed group in the frequency of death from leukemia or thyroid cancer, the causes of death most often associated with radiation exposure. Analysis of survival by recorded gamma radiation dose also did not show any effect of radiation dose on mortality. The findings are in agreement with the current scientific literature on the risk of death from exposure to low-dose radiation.

Marital status is an important social factor associated with increased mortality from cardiovascular disease (CVD) and all causes. However, there has been no study on the association of marital status with mortality in haemodialysis patients. We analysed data from a 5-year prospective cohort study of 1064 Japanese haemodialysis patients aged 30 years or older. Marital status was classified into three groups: married, single and divorced/widowed. Cox's regression was used to estimate multivariate hazard ratios (HRs) [95% confidence intervals (CIs)] for all-cause mortality and CVD mortality according to marital status after adjusting for age, sex, duration of haemodialysis, cause of renal failure, body mass index, systolic blood pressure, total cholesterol, high density lipoprotein-cholesterol, albumin, high-sensitivity C-reactive protein, co-morbid conditions, smoking, alcohol consumption, education levels and job status. Single patients had higher risks than married patients for mortality from all causes (HR = 1.51, 95% CI: 1.06-2.16) and mortality from CVD (HR = 1.68, 95% CI: 1.03-2.76), and divorced/widowed patients had a higher risk than married patients for mortality from CVD (HR = 1.73, 95% CI: 1.15-2.60). After stratification by age, single patients aged 30-59 years had significantly higher risks for all-cause mortality and CVD mortality. The findings suggest that single status is a significant predictor for all-cause mortality and CVD mortality and that divorced/widowed status is a significant predictor for CVD mortality in haemodialysis patients.

Household air pollution from use of cooking fuel and under-five mortality: The role of breastfeeding status and kitchen location in Pakistan

PubMed Central

2017-01-01

Household air pollution (HAP) mainly from cooking fuel is one of the major causes of respiratory illness and deaths among young children in low and middle-income countries like Pakistan. This study investigates for the first time the association between HAP from cooking fuel and under-five mortality using the 2013 Pakistan Demographic and Health Survey (PDHS) data. Multi-level logistic regression models were used to examine the association between HAP and under-five mortality in a total of 11,507 living children across four age-groups (neonatal aged 0–28 days, post-neonatal aged 1–11 months, child aged 12–59 months and under-five aged 0–59 months). Use of cooking fuel was weakly associated with total under-five mortality (OR = 1.22, 95%CI = 0.92–1.64, P = 0.170), with stronger associations evident for sub-group analyses of children aged 12–59 months (OR = 1.98, 95%CI = 0.75–5.25, P = 0.169). Strong associations between use of cooking fuel and mortality were evident (ORs >5) in those aged 12–59 months for households without a separate kitchen using polluting fuels, and in children whose mother never breastfed. The results of this study suggest that HAP from cooking fuel is associated with a modest increase in the risk of death among children under five years of age in Pakistan, but particularly in those aged 12–59 months, and those living in poorer socioeconomic conditions. To reduce exposure to cooking fuel which is a preventable determinant of under-five mortality in Pakistan, the challenge remains to promote behavioural interventions such as breastfeeding in infancy period, keeping young children away from the cooking area, and improvements in housing and kitchen design.

Social inequalities in cardiovascular disease mortality are described in this paper focusing on the results of the Studio Longitudinale Torinese (SLT), an investigation that links census data with the statistical data that are currently available. The overall results confirm that cardiovascular disease mortality is higher in less-advantaged socioeconomic groups, irrespectively of the social indicator used: education, social class, housing quality, job security. Stratified data shows less important inequalities among ischemic heart disease as compared to cerebrovascular mortality. The differences are even more complex when the age groups in the two genders are analyzed, revealing cohort effects. Overall, the results agree with the previous survey carried out by ISTAT on 1981 Italian mortality, which confirmed the variations in inequalities according to geographical areas, gender and age. Differences in access to the health system are likely to be related to the differences detected for geographical areas, while differences in personal history and attitude towards health-associated behavior should explain age and gender variations in inequalities. Equity must be included in the evaluation of preventive programs and health-care models. Epidemiological and social research should be encouraged to better understand the factors that influence inequalities in cardiovascular disease mortality and in the health status of the population at large.

The article presents evaluation of medical demographic and economic losses of population of the Krasnoyarskii kraii conditioned by mortality of lung cancer in 2010-2014 using DALY technology. In the Krasnoyarskii kraii, during 2010-2014 64,712 individuals died because of lung cancer. The mortality of male population surpasses corresponding indices of mortality of females up to 3.9 times. In the region, the standardized indicator mortality of lung cancer among males annually surpasses the same indicator among females at maximum up to 8.1 times. The DALY maximal absolute losses of among males were registered in 2010 and 2013 and fell on age group of 55-59 years and among females on the age group of 60-64 years in 2014. The maximal (up to 5.2 times) difference in values of DALY indicator was established in 2010 between male and female population. the maximal gap in in DALY indices between male and female population was established in the age of 55-59 years. Almost half of DALY losses among males was established in 2013 and among females in 2014. The total losses of gross regional product in the region because of mortality conditioned by lung cancer made up to 29.8 billions of rubles in 2010-2014.

The purpose of this study was to investigate factors related to self-rated health and to mortality among 2490 community-living elderly. Respondents were followed for 7.3 years for all-cause mortality. To compare the relative impact of each variable, we employed logistic regression analysis for self-rated health and Cox hazard analysis for mortality. Cox analysis stratified by gender, follow-up periods, age group, and functional status was also employed. Series of analysis found that factors associated with self-rated health and with mortality were not identical. Psychological factors such as perceived isolation at home or 'ikigai (one aspect of psychological well-being)' were associated with self-rated health only. Age, functional status, and social relations were associated both with self-rated health and mortality after controlling for possible confounders. Illnesses and functional status accounted for 35-40% of variances in the fair/poor self-rated health. Differences by gender and functional status were observed in the factors related to self-rated health. Overall, self-rated health effect on mortality was stronger for people with no functional impairment, for shorter follow-up period, and for young-old age group. Although, illnesses and functional status were major determinants of self-rated health, economical, psychological, and social factors were also related to self-rated health.

We evaluate the clinical, echographic and prognostic characteristics of infective endocarditis (IE) in a large population of elderly patients, and the results of surgical approach. Multicentric, prospective, observational cohort study with 961 consecutive left-sided IE: 356 patients aged ≥65 years were compared with 605 younger. Indications for cardiac surgery, potential surgical risk, time and outcome, were compared. Hospital-acquired endocarditis, comorbidity, renal failure and septic shock were more frequent in elderly, but embolisms were less. Intracardiac destruction and ventricular failure were similar in both groups, but significantly fewer elderly patients underwent cardiac surgery (36% vs 51%; p < 0.01), and this group showed a worse outcome (43.2% of mortality vs 27% in younger; p < 0.01), resulting age as an independent predictor of mortality (OR: 1.02 CI95%: 1.01-1.03). Compared with medical treatment, surgery showed lower percentages of mortality compared with medical treatment (23.3% vs 31.3%; p = 0.03) in younger group, but a high mortality was observed with both procedures (47.6% vs 40.3%; p = 0.1) in the elderly. Although similar percentages of heart failure and intracardiac complications, increasing age is associated with higher mortality in IE. Lower rates of surgical treatment and a worse outcome after operation are common features in elderly patients. Copyright © 2011 The British Infection Association. Published by Elsevier Ltd.

Hip fractures in the elderly are followed by considerable risk of functional decline and mortality. The purposes of this study were to (1) explore predictive factors of functional level at discharge, (2) evaluate 1-year mortality after hip fracture compared with that of the general population, and (3) evaluate the affect of early functional outcome on 1-year mortality in patients operated on for hip fractures. A total of 228 consecutive patients (average age, 77.6 ± 7.4 years) with hip fractures who met the inclusion criteria were enrolled in an open, prospective, observational cohort study. Functional level at discharge was measured with the motor Functional Independence Measure (FIM) score, which is the most widely accepted functional assessment measure in use in the rehabilitation community. Mortality rates in the study population were calculated in absolute numbers and as the standardized mortality ratio. Multivariate regression analysis was used to explore predictive factors for motor FIM score at discharge and for 1-year mortality adjusted for important baseline variables. Age, health status, cognitive level, preinjury functional level, and pressure sores after hip fracture surgery were independently related to lower discharge motor FIM scores. At 1-year followup, 57 patients (25%; 43 women and 14 men) had died. The 1-year hip fracture mortality rate compared with that of the general population was 31% in our population versus 7% for men and 23% in our population versus 5% for women 65 years or older. The 1-year standardized mortality rate was 341.3 (95% CI, 162.5-520.1) for men and 301.6 (95% CI, 212.4-391.8) for women, respectively. The all-cause mortality rate observed in this group was higher in all age groups and in both sexes when compared with the all-cause age-adjusted mortality of the general population. Motor FIM score at discharge was the only independent predictor of 1-year mortality after hip fracture. Functional level at discharge is the main determinant of long-term mortality in patients with hip fracture. Motor FIM score at discharge is a reliable predictor of mortality and can be recommended for clinical use.

The relation of knee replacement (KR) surgery to all-cause mortality has not been well established owing to potential biases in previous studies. Thus, we aimed to examine the relation of KR to mortality risk among patients with knee osteoarthritis (OA) focusing on identifying biases that may threaten the validity of prior studies. We included knee OA subjects (ages 50-89 years) from The Health Improvement Network, an electronic medical records database in the UK. Risk of mortality among KR subjects was compared with propensity score-matched non-KR subjects. To explore residual confounding bias, subgroup analyses stratified by age and propensity scores were performed. Subjects with KR had 28% lower risk of mortality than non-KR subjects (HR 0.72, 95% CI 0.66 to 0.78). However, when stratified by age, protective effect was noted only in older age groups (>63 years) but not in younger subjects (≤63 years). Further, the mortality rate among KR subjects decreased as candidacy (propensity score) for KR increased among subjects with KR, but no such consistent trend was noted among non-KR subjects. While a protective effect of KR on mortality cannot be ruled out, findings of lower mortality among older KR subjects and those with higher propensity scores suggest that prognosis-based selection for KR may lead to intractable confounding by indication; hence, the protective effect of KR on all-cause mortality may be overestimated.

The elderly and persons with specific chronic conditions are known to face elevated morbidity and mortality risks resulting from an influenza infection, and hence are routinely recommended for annual influenza vaccination. However, risk-specific mortality rates have not been established. We estimated age-specific influenza-attributable mortality rates stratified by the presence of chronic conditions and type of residence based on deaths of persons who were admitted to hospital with a respiratory complication captured in our national database. The majority of patients had chronic heart or respiratory conditions (80%) and were admitted from the community (80%). Influenza-attributable mortality rates clearly increase with age for all risk groups. Our influenza-specific estimates identified higher risk ratios for chronic lung or heart disease than have been suggested by other methods. These estimates identify groups most in need of improved vaccines and for whom the use of additional strategies, such as immunization of household contacts or caregivers should be considered.

Mortality by skin color/race and urbanity of Brazilian cities.

The skin color/race and urbanity are structural determinants of health. The relationship between these variables produces structure of social stratification that defines inequalities in the experiences of life and death. Thus, this study describes the characteristics of the mortality indicators by skin color/race according level of urbanity and aggregation to the metropolitan region (MR) of 5565 cities in Brazil, controlling for gender and age. Descriptive study which included the calculation of measures relating to 1,050,546 deaths in the year survey of 2010 by skin color/race White, Black, and Brown according to both sexes, for five age groups and three levels of urbanity of cities in Brazil that were aggregated or not to the MR in the year of study. The risk of death was estimated by calculating premature mortality rate (PMR) at 65 years of age, per 100,000 and age adjusted. The structure of mortality by skin color/race Black and Brown reflects worse levels of health and excessive premature deaths, with worse situation for men. The Whites, especially women, tend to live longer and in better health than other racial groups. The age-adjusted PMR indicates distinct risk of death by skin color/race, this risk was higher in men than in women and in Blacks than in other racial groups of both sexes. There have been precarious levels of health in the urban space and the MR has intensified these inequalities. The research pointed out that the racial inequality in the mortality was characterized by interaction of race with other individual and contextual determinants of health. Those Blacks and Browns are the groups most vulnerable to the iniquities associated with occurrence of death, but these differences in the profile and the risk of death depend on the level of urbanity and aggregation MR of Brazilian cities in 2010.

Suicide is a major cause of premature death in Italy and occurs at different rates in the various regions. The aim of the present study was to provide a comprehensive overview of suicide in the Italian population aged 15 years and older for the years 1980-2006. Mortality data were extracted from the Italian Mortality Database. Mortality rates for suicide in Italy reached a peak in 1985 and declined thereafter. The different patterns observed by age and sex indicated that the decrease in the suicide rate in Italy was initially the result of declining rates in those aged 45+ while, from 1997 on, the decrease was attributable principally to a reduction in suicide rates among the younger age groups. It was found that socioeconomic factors underlined major differences in the suicide rate across regions. The present study confirmed that suicide is a multifaceted phenomenon that may be determined by an array of factors. Suicide prevention should, therefore, be targeted to identifiable high-risk sociocultural groups in each country.

Poisoning due to pesticides is an important public health problem worldwide due its morbidity and mortality. In Colombia, there are no exact data on mortality due to pesticide poisoning. To estimate the trend of mortality rate due to pesticide poisoning in Colombia between 1998 and 2011. We carried out a descriptive analysis with the database reports of death as unintentional poisoning, self-inflicted intentional poisoning, aggression with pesticides, and poisoning with non-identified intentionality, population projections between 1998 and 2011, and rurality indexes. Crude and age-adjusted mortality rates were estimated and trends and Spearman coefficients were evaluated. A total of 4,835 deaths were registered (age-adjusted mortality rate of 2.38 deaths per 100,000 people). Mortality rates were higher in rural areas, for self-inflicted intentional poisoning, in men and in age groups between 15 and 39 years old. The trend has been decreasing since 2002. Municipality mortality rates due to unintentional poisoning and aggression correlated significantly with the rurality index in less rural municipalities. Mortality rates due to pesticide poisoning presented a mild decrease between 1998 and 2011. It is necessary to adjust and reinforce the measures conducive to reducing pesticide exposure in order to avoid poisoning and reduce mortality.

In the German population, the percentage of elderly patients is increasing, and consequently there are more elderly patients among trauma cases, and particularly cases of polytrauma. The aim of this study was to present clinical results and a risk profile for geriatric polytrauma patients. Review of 140 geriatric (over 65 years of age) polytrauma patients who received prehospital treatment was performed. Severity of trauma was retrospectively assessed with Hannover Polytrauma Score (HPTS). Age, hemoglobin (Hb) level, systolic blood pressure (BP), Glasgow Coma Scale (GCS) score, timing of and necessity for intubation were analyzed in relation to mortality and in comparison with younger patients. Geriatric polytrauma patients (n=140) had overall mortality rate of 65%, whereas younger patients (n=1468) had mortality rate of 15.9%. Despite equivalent severity of injury (HPTS less age points) in geriatric and non-geriatric groups, mortality rate was 4 times higher in geriatric group. Major blood loss with Hb <8 g/dL was revealed to be 3 times more fatal than moderate or minor blood loss (Hb ≥8 g/dL). GCS score <12 corresponded to double mortality rate (39% vs 83%). Age by itself is significant risk factor and predictor of increased mortality in polytrauma patients. Additional risk factors include very low GCS score and systolic BP <80 mm Hg, for instance, as potential clinical indicators of massive bleeding and traumatic brain injury. Such parameters demand early and rapid treatment at prehospital stage and on admission.

Multiple Sclerosis (MS) is a leading cause of disability among young Americans. Reports suggest that life expectancy (i.e., average age at death) remains reduced as compared to the general population, but underlying causes of death (UCOD) are less well-characterized. To describe the cause-specific mortality among participants enrolled in the North American Research Committee on Multiple Sclerosis (NARCOMS) registry and to compare the profile of these causes by age, sex, race and disability status at entry into NARCOMS, with U.S. mortality data. The underlying cause of death (UCOD), any mention cause of death and proportionate mortality were compared among U.S. NARCOMS participants by age, sex, race and disability status. Of the 32,445 participants to be considered for this study, 2,927 had died. Compared to survivors, decedents were older at enrollment and MS diagnosis, more likely to be male, and had less education. UCOD differed markedly by age group. In both sexes, MS as the UCOD was proportionately lower by 20% or more in those aged 25-39 compared to those aged 75 or older. Cancer and cardiovascular causes were more frequent as causes of death with increasing age, but were less than expected at older ages. The effect of disability on mortality was roughly equivalent to the effect of aging on mortality. Among NARCOMS participants older age at enrollment, male sex and greater disability were associated with increased mortality risk. This cohort of MS subjects had a lower proportionate mortality from cardiovascular disease and cancer compared to the U.S. population. Copyright © 2015 Elsevier B.V. All rights reserved.

A comparison was made of the outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (AVR) in high-risk patients. All patients aged > 75 years that underwent a procedure for severe aortic stenosis with or without coronary revascularization at the authors' institution were included in the study; thus, 64 patients underwent TAVI and 188 underwent AVR. Patients in the TAVI group were older (mean age 84 +/- 5 versus 80 +/- 4 years; p < 0.0001) and had a higher logistic EuroSCORE (p = 0.004). Six patients (9%) died during the procedure in the TAVI group, and 23 (12%) died in the AVR group (p = 0.5). Predictors for mortality were: age (p < 0.0001), female gender (p = 0.02), and surgical valve replacement (p = 0.01). Gradients across the implanted valves at one to three months postoperatively were lower in the TAVI group (p < 0.0001). Actuarial survival at one, two and three years was 78%, 64% and 64%, respectively, for TAVI, and 83%, 78% and 75%, respectively, for AVR (p = 0.4). Age was the only predictor for late mortality (p < 0.0001). TAVI patients were older and posed a higher predicted surgical risk. Procedural mortality was lower in the TAVI group, but mid-term survival was similar to that in patients undergoing surgical AVR. Age was the only predictor for late survival. These data support the referral of high-risk patients for TAVI.

Left ventricular assist devices (LVAD) are increasingly used, especially as destination therapy in in older patients. The aim of this study was to evaluate the effect of age on renal function and mortality in the first year after implantation. A retrospective multicenter cohort study was conducted, evaluating all LVAD patients implanted in the 2 participating centers (age ≥18 years). Patients were stratified according to the age groups <45, 45-54, 55-64, and ≥65 years old. Overall, 241 patients were included (mean age 52.4 ± 12.9 years, 76% males, 33% destination therapy). The mean estimated Glomerular Filtration Rate (eGFR) at 1 year was 85, 72, 69, and 49 mL/min per 1.73 m 2 in the age groups <45(n = 65, 27%), 45-54(n = 52, 22%), 55-64(n = 87, 36%), and ≥65 years (n = 37, 15%) p <0.001)), respectively. Older age and lower eGFR at baseline (p <0.01) were independent predictors of worse renal function at 1 year. The 1-year survival post-implantation was 79%,84%, 68%, and 54% for those in the age group <45, 45-54, 55-64 and ≥65 years (Log-rank p = 0.003). Older age, lower eGFR and, INTERMACS class I were independent predictors of 1-year mortality. Furthermore, older patients (age > 60 years) with an impaired renal function (eGFR <55 mL/min per 1.73 m 2 ) had a 5-fold increased hazard ratio for mortality during the first year after implantation (p <0.001). In conclusion, age >60 years is an independent predictor for an impaired renal function and mortality. Older age combined with reduced renal function pre-implantation had a cumulative adverse effect on survival in patients receiving a LVAD. Copyright © 2017 Elsevier Inc. All rights reserved.

The aims of this study were to estimate mortality rates in Norwegian dairy calves and young stock up to 1 yr of age, identify risk factors for calf mortality, and evaluate the etiology of calf mortality based on postmortem analyses. The material comprised 3 data sets. The first data set included information on 289,038 offspring in 14,474 dairy herds registered in the Norwegian Dairy Herd Recording System (NDHRS) in 2005. The second included recordings on 5,382 offspring in 125 Norwegian dairy herds participating in a survey on calf health, and the third included results from postmortem analyses of 65 calves from 37 of the survey herds. The calf mortality rate during the first year of life in all herds registered in the NDHRS was 7.8%, including abortion (0.7%) and stillbirth (3.4%). The overall calf mortality rate in liveborn calves in the survey herds was 4.6%. Cows with severe calving difficulties had an odds ratio (OR) of 38.7 of stillbirth compared with cows with no calving difficulties. Twins and triplets showed an increased risk of stillbirth compared with singletons (OR = 4.2 and 46.3, respectively), as did calves born in free stalls compared with tie stalls (OR = 1.9). Respiratory disease increased the risk of death in all age groups with hazard ratios (HR) of 6.4, 6.5, 7.4, and 5.6 during the first week of life, 8 to 30 d of age, 31 to 180 d of age, and 181 to 365 d of age, respectively. Diarrhea increased the risk of death among calves younger than 180 d of age, but the influence was only significant during the first week of life and between 8 to 31 d of age (HR = 2.4 and 2.9, respectively). Calves born during the winter were more likely to die during the first week of life than calves born during the summer (OR = 1.2), and were more likely to die during the first month of life than calves born during the autumn (OR = 1.2). Calf mortality rates in all age groups increased with increasing herd size. Calves housed in a group pen from 2 wk of age were more likely to die during the first month of life than calves housed individually (HR = 1.5). Bronchopneumonia and enteritis were the most frequent postmortem diagnoses, with proportional rates of 27.7 and 15.4%, respectively.

Objectives. We sought to determine whether chronic conditions and functional limitations are equally predictive of mortality among older adults. Methods. Participants in the 1998 wave of the Health and Retirement Study (N=19430) were divided into groups by decades of age, and their vital status in 2004 was determined. We used multivariate Cox regression to determine the ability of chronic conditions and functional limitations to predict mortality. Results. As age increased, the ability of chronic conditions to predict mortality declined rapidly, whereas the ability of functional limitations to predict mortality declined more slowly. In younger participants (aged 50–59 years), chronic conditions were stronger predictors of death than were functional limitations (Harrell C statistic 0.78 vs. 0.73; P=.001). In older participants (aged 90–99 years), functional limitations were stronger predictors of death than were chronic conditions (Harrell C statistic 0.67 vs. 0.61; P=.004). Conclusions. The importance of chronic conditions as a predictor of death declined rapidly with increasing age. Therefore, risk-adjustment models that only consider comorbidities when comparing mortality rates across providers may be inadequate for adults older than 80 years. PMID:18511714

Socioeconomic inequalities in mortality from conditions amenable to medical interventions: do they reflect inequalities in access or quality of health care?

PubMed Central

2012-01-01

Background Previous studies have reported large socioeconomic inequalities in mortality from conditions amenable to medical intervention, but it is unclear whether these can be attributed to inequalities in access or quality of health care, or to confounding influences such as inequalities in background risk of diseases. We therefore studied whether inequalities in mortality from conditions amenable to medical intervention vary between countries in patterns which differ from those observed for other (non-amenable) causes of death. More specifically, we hypothesized that, as compared to non-amenable causes, inequalities in mortality from amenable causes are more strongly associated with inequalities in health care use and less strongly with inequalities in common risk factors for disease such as smoking. Methods Cause-specific mortality data for people aged 30–74 years were obtained for 14 countries, and were analysed by calculating age-standardized mortality rates and relative risks comparing a lower with a higher educational group. Survey data on health care use and behavioural risk factors for people aged 30–74 years were obtained for 12 countries, and were analysed by calculating age-and sex-adjusted odds ratios comparing a low with a higher educational group. Patterns of association were explored by calculating correlation coefficients. Results In most countries and for most amenable causes of death substantial inequalities in mortality were observed, but inequalities in mortality from amenable causes did not vary between countries in patterns that are different from those seen for inequalities in non-amenable mortality. As compared to non-amenable causes, inequalities in mortality from amenable causes are not more strongly associated with inequalities in health care use. Inequalities in mortality from amenable causes are also not less strongly associated with common risk factors such as smoking. Conclusions We did not find evidence that inequalities in mortality from amenable conditions are related to inequalities in access or quality of health care. Further research is needed to find the causes of socio-economic inequalities in mortality from amenable conditions, and caution should be exercised in interpreting these inequalities as indicating health care deficiencies.

Projection of future temperature-related mortality due to climate and demographic changes.

PubMed

Lee, Jae Young; Kim, Ho

2016-09-01

Understanding the effects of global climate change from both environmental and human health perspectives has gained great importance. Particularly, studies on the direct effect of temperature increase on future mortality have been conducted. However, few of those studies considered population changes, and although the world population is rapidly aging, no previous study considered the effect of society aging. Here we present a projection of future temperature-related mortality due to both climate and demographic changes in seven major cities of South Korea, a fast aging country, until 2100; we used the HadGEM3-RA model under four Representative Concentration Pathway (RCP) scenarios (RCP 2.6, 4.5, 6.0, and 8.5) and the United Nations world population prospects under three fertility scenarios (high, medium, and low). The results showed markedly increased mortality in the elderly group, significantly increasing the overall future mortality. In 2090s, South Korea could experience a four- to six-time increase in temperature-related mortality compared to that during 1992-2010 under four different RCP scenarios and three different fertility variants, while the mortality is estimated to increase only by 0.5 to 1.5 times assuming no population aging. Therefore, not considering population aging may significantly underestimate temperature risks. Copyright © 2016 Elsevier Ltd. All rights reserved.

Mortality and morbidity in the 21st century

PubMed Central

Case, Anne; Deaton, Angus

2017-01-01

SUMMARY We build on and extend the findings in Case and Deaton (2015) on increases in mortality and morbidity among white non-Hispanic Americans in midlife since the turn of the century. Increases in all-cause mortality continued unabated to 2015, with additional increases in drug overdoses, suicides, and alcohol-related liver mortality, particularly among those with a high-school degree or less. The decline in mortality from heart disease has slowed and, most recently, stopped, and this combined with the three other causes is responsible for the increase in all-cause mortality. Not only are educational differences in mortality among whites increasing, but from 1998 to 2015 mortality rose for those without, and fell for those with, a college degree. This is true for non-Hispanic white men and women in all five year age groups from 35–39 through 55–59. Mortality rates among blacks and Hispanics continued to fall; in 1999, the mortality rate of white non-Hispanics aged 50–54 with only a high-school degree was 30 percent lower than the mortality rate of blacks in the same age group but irrespective of education; by 2015, it was 30 percent higher. There are similar crossovers in all age groups from 25–29 to 60–64. Mortality rates in comparable rich countries have continued their pre-millennial fall at the rates that used to characterize the US. In contrast to the US, mortality rates in Europe are falling for those with low levels of educational attainment, and have fallen further over this period than mortality rates for those with higher levels of education. Many commentators have suggested that poor mortality outcomes can be attributed to contemporaneous levels of resources, particularly to slowly growing, stagnant, and even declining incomes; we evaluate this possibility, but find that it cannot provide a comprehensive explanation. In particular, the income profiles for blacks and Hispanics, whose mortality rates have fallen, are no better than those for whites. Nor is there any evidence in the European data that mortality trends match income trends, in spite of sharply different patterns of median income across countries after the Great Recession. We propose a preliminary but plausible story in which cumulative disadvantage from one birth cohort to the next, in the labor market, in marriage and child outcomes, and in health, is triggered by progressively worsening labor market opportunities at the time of entry for whites with low levels of education. This account, which fits much of the data, has the profoundly negative implication that policies, even ones that successfully improve earnings and jobs, or redistribute income, will take many years to reverse the mortality and morbidity increase, and that those in midlife now are likely to do much worse in old age than those currently older than 65. This is in contrast to an account in which resources affect health contemporaneously, so that those in midlife now can expect to do better in old age as they receive Social Security and Medicare. None of this implies that there are no policy levers to be pulled; preventing the over-prescription of opioids is an obvious target that would clearly be helpful. PMID:29033460

Despite the importance of socioeconomic position for survival, total wealth, which is a measure of accumulation of assets over the life course, has been underinvestigated as a predictor of mortality. We investigated the association between total wealth and mortality at older ages. We estimated Cox proportional hazards models using a sample of 10,305 community-dwelling individuals aged ≥ 50 years from the English Longitudinal Study of Ageing. 2401 deaths were observed over a mean follow-up of 9.4 years. Among participants aged 50-64 years, the fully adjusted HRs for mortality were 1.21 (95% CI 0.92 to 1.59) and 1.77 (1.35 to 2.33) for those in the intermediate and lowest wealth tertiles, respectively, compared with those in the highest wealth tertile. The respective HRs were 2.54 (1.27 to 5.09) and 3.73 (1.86 to 7.45) for cardiovascular mortality and 1.36 (0.76 to 2.42) and 2.53 (1.45 to 4.41) for other non-cancer mortality. Wealth was not associated with cancer mortality in the fully adjusted model. Similar but less strong associations were observed among participants aged ≥ 65 years. The use of repeated measurements of wealth and covariates brought about only minor changes, except for the association between wealth and cardiovascular mortality, which became less strong in the younger participants. Wealth explained the associations between paternal occupation at age 14 years, education, occupational class, and income and mortality. There are persisting wealth inequalities in mortality at older ages, which only partially are explained by established risk factors. Wealth appears to be more strongly associated with mortality than other socioeconomic position measures. Published by the BMJ Publishing Group Limited.

We assessed differences in predicted breast cancer (BC) mortality rates, across Europe, by 2020, taking into account changes in the time trends of BC mortality rates during the period 2000-2010. BC mortality data, for 27 European Union (EU) countries, were extracted from the World Health Organization mortality database. First, we compared BC mortality data between time periods 2000-2004 and 2006-2010 through standardized mortality ratios (SMRs) and carrying out a graphical assessment of the age-specific rates. Second, making use of the base period 2006-2012, we predicted BC mortality rates by 2020. Finally, making use of the SMRs and the predicted data, we identified a clustering of countries, assessing differences in the time trends between the areas defined in this clustering. The clustering approach identified two clusters of countries: the first cluster were countries where BC predicted mortality rates, in 2020, might slightly increase among women aged 69 and older compared with 2010 [Greece (SMR 1.01), Croatia (SMR 1.02), Latvia (SMR 1.15), Poland (SMR 1.14), Estonia (SMR 1.16), Bulgaria (SMR 1.13), Lithuania (SMR 1.03), Romania (SMR 1.13) and Slovakia (SMR 1.06)]. The second cluster was those countries where BC mortality rates level off or decrease in all age groups (remaining countries). However, BC mortality rates between these clusters might diminish and converge to similar figures by 2020. For the year 2020, our predictions have shown a converging pattern of BC mortality rates between European regions. Reducing disparities, in access to screening and treatment, could have a substantial effect in countries where a non-decreasing trend in age-specific BC mortality rates has been predicted.

Trollor, Julian; Srasuebkul, Preeyaporn; Xu, Han; Howlett, Sophie

2017-02-07

To investigate mortality and its causes in adults over the age of 20 years with intellectual disability (ID). Retrospective population-based standardised mortality of the ID and Comparison cohorts. The ID cohort comprised 42 204 individuals who registered for disability services with ID as a primary or secondary diagnosis from 2005 to 2011 in New South Wales (NSW). The Comparison cohort was obtained from published deaths in NSW from the Australian Bureau of Statistics (ABS) from 2005 to 2011. We measured and compared Age Standardised Mortality Rate (ASMR), Comparative Mortality Figure (CMF), years of productive life lost (YPLL) and proportion of deaths with potentially avoidable causes in an ID cohort with an NSW general population cohort. There were 19 362 adults in the ID cohort which experienced 732 (4%) deaths at a median age of 54 years. Age Standardised Mortality Rates increased with age for both cohorts. Overall comparative mortality figure was 1.3, but was substantially higher for the 20-44 (4.0) and 45-64 (2.3) age groups. YPLL was 137/1000 people in the ID cohort and 49 in the comparison cohort. Cause of death in ID cohort was dominated by respiratory, circulatory, neoplasm and nervous system. After recoding deaths previously attributed to the aetiology of the disability, 38% of deaths in the ID cohort and 17% in the comparison cohort were potentially avoidable. Adults with ID experience premature mortality and over-representation of potentially avoidable deaths. A national system of reporting of deaths in adults with ID is required. Inclusion in health policy and services development and in health promotion programmes is urgently required to address premature deaths and health inequalities for adults with ID.

Tarnutzer, Silvan; Bopp, Matthias

2012-12-22

In many countries, migrants from Italy form a substantial, well-defined group with distinct lifestyle and dietary habits. There is, however, hardly any information about all-cause mortality patterns among Italian migrants and their offspring. In this paper, we compare Italian migrants, their offspring and Swiss nationals. We compared age-specific and age-standardized mortality rates and hazard ratios (adjusted for education, marital status, language region and period) for Swiss and Italian nationals registered in the Swiss National Cohort (SNC), living in the German- or French-speaking part of Switzerland and falling into the age range 40-89 during the observation period 1990-2008. Overall, 3,175,288 native Swiss (48% male) and 224,372 individuals with an Italian migration background (57% male) accumulated 698,779 deaths and 44,836,189 person-years. Individuals with Italian background were categorized by nationality, country of birth and language. First-generation Italians had lower mortality risks than native Swiss (reference group), but second-generation Italians demonstrated higher mortality risks. Among first-generation Italians, predominantly Italian-speaking men and women had hazard ratios (HRs) of 0.89 (95% CI: 0.88-0.91) and 0.90 (0.87-0.92), respectively, while men and women having adopted the regional language had HRs of 0.93 (0.88-0.98) and 0.96 (0.88-1.04), respectively. Among second-generation Italians, the respective HRs were 1.16 (1.03-1.31), 1.06 (0.89-1.26), 1.10 (1.05-1.16) and 0.97 (0.89-1.05). The mortality advantage of first-generation Italians decreased with age. The mortality risks of first- and second-generation Italians vary substantially. The healthy migrant effect and health disadvantage among second-generation Italians show characteristic age/sex patterns. Future investigation of health behavior and cause-specific mortality is needed to better understand different mortality risks. Such insights will facilitate adequate prevention and health promotion efforts.

Ghana's maternal mortality ratio remains high despite efforts made to meet Millennium Development Goal 5. A number of studies have been conducted on maternal mortality in Ghana; however, little is known about how the causes of maternal mortality are distributed in different socio-demographic subgroups. Therefore the aim of this study was to assess and analyse the causes of maternal mortality according to socio-demographic factors in Ghana. The causes of maternal deaths were assessed with respect to age, educational level, rural/urban residence status and marital status. Data from a five year retrospective survey was used. The data was obtained from Ghana Maternal Health Survey 2007 acquired from the database of Ghana Statistical Service. A total of 605 maternal deaths within the age group 12-49 years were analysed using frequency tables, cross-tabulations and logistic regression. Haemorrhage was the highest cause of maternal mortality (22.8%). Married women had a significantly higher risk of dying from haemorrhage, compared with single women (adjusted OR = 2.7, 95%CI = 1.2-5.7). On the contrary, married women showed a significantly reduced risk of dying from abortion compared to single women (adjusted OR = 0.2, 95%CI = 0.1-0.4). Women aged 35-39 years had a significantly higher risk of dying from haemorrhage (aOR 2.6, 95%CI = 1.4-4.9), whereas they were at a lower risk of dying from abortion (aOR 0.3, 95% CI = 0.1-0.7) compared to their younger counterparts. The risk of maternal death from infectious diseases decreased with increasing maternal age, whereas the risk of dying from miscellaneous causes increased with increasing age. The study shows evidence of variations in the causes of maternal mortality among different socio-demographic subgroups in Ghana that should not be overlooked. It is therefore recommended that interventions aimed at combating the high maternal mortality in Ghana should be both cause-specific as well as target-specific.

Age-specific mortality trends in France and Italy since 1900: period and cohort effects.

Caselli, G; Vallin, J; Vaupel, J W; Yashin, A

1987-11-01

The age/sex-specific mortality trends of France and Italy were studied over the 1899-1979 period in as much detail as possible in an effort to distinguish between cohort effects and those related to period changes. Complete series of mortality data by individual years of age and calendar years were available from 1869 to 1979 for Italy and from 1899 to 1982 for France. For both countries, these data include the military and civil deaths not registered in vital statistics during the war periods. They cover each national territory as defined by its present boundaries. The graphical representation method of mortality surfaces, elaborated by Vaupel, Gambill, and Yashin (1985), was adopted. The age/sex-specific mortality patterns of France and Italy have not followed the same trends, and the differences observed today are not those of 100 years ago. The mean death probabilities for the 1975-79 period were used to illustrate the age-specific patterns of mortality. Although infant mortality was higher in Italy than in France, the death probabilities at ages 1-15 for both sexes were roughly the same for both countries. At ages 15-23, they were much higher in France than in Italy, and they remained considerably higher in France up to age 55. From then on, the sexes differ: for males, the 2 countries showed similar patterns, whereas for females the probabilities were noticeably higher for France. The situation was very different for both countries at the beginning of the century. For both sexes, higher mortality was observed in Italy not only during infancy but throughout childhood and the adolescent years up to age 15. The 2 countries showed similar patterns from 15-25. Above age 25, the 2 countries had similar patterns for females, whereas male mortality was higher in France right up to the old age groups. Such differences in the age-specific mortality trends depend in part on a different development of health and social conditions but also may be due to factors concerning the history of particular groups of generations. The general health progress made in both countries has played an important role but, on the whole, a more favorable role in Italy. Italy's infant and child mortality have drawn nearer the French level, while it has increased its advantage regarding adult mortality. France has strengthened its position only at older ages. There have been many perturbations since 1900, the most important of which has been the 2 world wars. They affected the 2 countries differently both in terms of their immediate effects on both the civil and military populations and in the longterm effects on the cohorts that had suffered most. These cohort effects, largely related to World War I, seem to have disappeared at this time, most likely in part because of selection relevelling the chances of survival of the various cohorts and in part because of general health progress masking the slight differences that may remain.

Illiteracy, low educational status, and cardiovascular mortality in India

2011-01-01

Background Influence of education, a marker of SES, on cardiovascular disease (CVD) mortality has not been evaluated in low-income countries. To determine influence of education on CVD mortality a cohort study was performed in India. Methods 148,173 individuals aged ≥ 35 years were recruited in Mumbai during 1991-1997 and followed to ascertain vital status during 1997-2003. Subjects were divided according to educational status into one of the five groups: illiterate, primary school (≦ 5 years of formal education), middle school (6-8 years), secondary school (9-10 years) and college (> 10 years). Multivariate analyses using Cox proportional hazard model was performed and hazard ratios (HRs) and 95% confidence intervals (CIs) determined. Results At average follow-up of 5.5 years (774,129 person-years) 13,261 deaths were observed. CVD was the major cause of death in all the five educational groups. Age adjusted all-cause mortality per 100,000 in illiterate to college going men respectively was 2154, 2149, 1793, 1543 and 1187 and CVD mortality was 471, 654, 618, 518 and 450; and in women all-cause mortality was 1444, 949, 896, 981 and 962 and CVD mortality was 429, 301, 267, 426 and 317 (ptrend < 0.01). Compared with illiterate, age-adjusted HRs for CVD mortality in primary school to college going men were 1.36, 1.27, 1.01 and 0.88 (ptrend < 0.05) and in women 0.69, 0.55, 1.04 and 0.74, respectively (ptrend > 0.05). Conclusions Inverse association of literacy status with all-cause mortality was observed in Indian men and women, while, for CVD mortality it was observed only in men. PMID:21756367

To compare the ability of two diagnosis-based risk adjustment systems and health self-report to predict short- and long-term mortality. Data were obtained from the Department of Veterans Affairs (VA) administrative databases. The study population was 78,164 VA beneficiaries at eight medical centers during fiscal year (FY) 1998, 35,337 of whom completed an 36-Item Short Form Health Survey for veterans (SF-36V) survey. We tested the ability of Diagnostic Cost Groups (DCGs), Adjusted Clinical Groups (ACGs), SF-36V Physical Component score (PCS) and Mental Component Score (MCS), and eight SF-36V scales to predict 1- and 2-5 year all-cause mortality. The additional predictive value of adding PCS and MCS to ACGs and DCGs was also evaluated. Logistic regression models were compared using Akaike's information criterion, the c-statistic, and the Hosmer-Lemeshow test. The c-statistics for the eight scales combined with age and gender were 0.766 for 1-year mortality and 0.771 for 2-5-year mortality. For DCGs with age and gender the c-statistics for 1- and 2-5-year mortality were 0.778 and 0.771, respectively. Adding PCS and MCS to the DCG model increased the c-statistics to 0.798 for 1-year and 0.784 for 2-5-year mortality. The DCG model showed slightly better performance than the eight-scale model in predicting 1-year mortality, but the two models showed similar performance for 2-5-year mortality. Health self-report may add health risk information in addition to age, gender, and diagnosis for predicting longer-term mortality.

Health self-report may add health risk information in addition to age, gender, and diagnosis for predicting longer-term mortality. PMID:17362210

To determine if dizziness is an independent risk factor for mortality among adults in the United States. Cross-sectional analysis using the National Health Interview Survey (NHIS). Adult respondents in the 2008 NHIS were evaluated. Demographic information (gender, race, ethnicity, education level), prevalence of dizziness, mortality rates, and leading causes of death (cardiovascular disease, cancer, diabetes, cerebrovascular disease) were collected and analyzed. The association between dizziness and subsequent mortality was determined adjusting for demographic and other disease factors. Among 213.6 ± 3.5 million adult Americans, 23.8 ± 0.7 million reported dizziness in the past 12 months (11.1% ± 0.3%; mean age, 45.9 ± 0.2 years; 51.7% ± 0.5% female). The mortality rate among the group without dizziness in the preceding 12 months was 2.6% ± 0.1%, compared to the dizzy group at 9.0% ± 0.7%. After adjusting for gender and age, there was a statistically significant association between dizziness and mortality (odds ratio [OR]: 2.2, 95% confidence interval [CI]: 1.8-2.8). After adjusting for all covariates including age, ethnicity, race, gender, diabetes, cardiovascular, cerebrovascular disease, cancer, and grade level, dizziness remained an independent predictor of increased mortality (adjusted OR: 1.7, 95% CI: 1.36-2.18). Approximately 11% of adult Americans reported dizziness or balance problems in the preceding 12 months. Adults with dizziness have a greater mortality rate than nondizzy adults. Even after adjusting for covariates, there was a significant association between dizziness and mortality. Screening for dizziness as a risk factor for mortality may be warranted. 2b Laryngoscope, 126:2134-2136, 2016. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

There is a lack of evidence to compare in-hospital mortality with different types of stroke. The purpose of this study was to elucidate the in-hospital mortality after acute ischemic/hemorrhagic stroke and compare the factors associated with the mortality among stroke subtypes. All patients admitted to Kurashiki Central Hospital in Japan between January 2009 and December 2009, and diagnosed with acute ischemic/hemorrhagic stroke were included in this study. Demographics and clinical data pertaining to the patients were obtained from their medical records. Out of 738 patients who had an acute stroke, 53 (7.2%) died in the hospital. The in-hospital mortality was significantly lower in the cerebral infarction group than in the intracerebral hemorrhage and subarachnoid hemorrhage group (3.5%, 15.1%, and 17.9%, respectively; P<0.0001). Age was significantly lower in the subarachnoid hemorrhage group than in the other 2 groups. With regard to past history, diabetes mellitus was significantly found to be a complication in mortality cases of intracranial hemorrhage. Further investigation is needed to clarify the effect of diabetes on mortality after intracranial hemorrhage.

Objectives We carried out an evaluation of a large-scale New Zealand retrofit programme using administrative data that provided the statistical power to assess the effect of insulation and/or heating retrofits on cardiovascular and respiratory-related mortality in people aged 65 and over with prior respiratory or circulatory hospitalisations. Design Quasi-experimental cohort study based on administrative data. Setting New Zealand. Participants From a larger study cohort of over 900 000 people, we selected two subcohorts: 3287 people who were aged 65 and over and had experienced pretreatment period cardiovascular-related hospitalisation (ICD-10 chapter 9), and 1561 people aged 65 and over who had experienced pretreatment respiratory-related hospitalisation (ICD-10 chapter 10). Interventions Treatment group individuals lived in a home that received insulation and/or heating retrofits under the Warm Up New Zealand: Heat Smart programme. Control group individuals lived in a home that was matched to a treatment home based on physical characteristics and location. Primary and secondary outcome measures HR for all-cause mortality for treatment with insulation, heating, or insulation and heating relative to control group. Results People with pretreatment circulatory hospitalisation who occupied a household that received only insulation had an HR for all-cause mortality of 0.673 (95% CI 0.535 to 0.847) (p<0.001) relative to control group members. Individuals with a pretreatment respiratory hospitalisation who occupied a household that received only an insulation retrofit had an HR for all-cause mortality of 0.830 (95% CI 0.655 to 1.051) (p=0.122) relative to control group members. There was no evidence of an additional benefit from receiving heating. Conclusions We interpret the hazard rate observed for cardiovascular subcohort individuals who received insulation as evidence of a protective effect, reducing the risk of mortality for vulnerable older adults. There is suggestive evidence of a protective effect of insulation for the respiratory subcohort. PMID:29138207

During the past decades a widening of the relative gap in death rates between upper and lower socioeconomic groups has been reported for several European countries. Although differential mortality decline for cardiovascular diseases has been suggested as an important contributory factor, it is not known what its quantitative contribution was, and to what extent other causes of death have contributed to the widening gap in total mortality. We collected data on mortality by educational level and occupational class among men and women from national longitudinal studies in Finland, Sweden, Norway, Denmark, England/Wales, and Italy (Turin), and analysed age-standardized death rates in two recent time periods (1981-1985 and 1991-1995), both total mortality and by cause of death. For simplicity, we report on inequalities in mortality between two broad socioeconomic groups (high and low educational level, non-manual and manual occupations). Relative inequalities in total mortality have increased in all six countries, but absolute differences in total mortality were fairly stable, with the exception of Finland where an increase occurred. In most countries, mortality from cardiovascular diseases declined proportionally faster in the upper socioeconomic groups. The exception is Italy (Turin) where the reverse occurred. In all countries with the exception of Italy (Turin), changes in cardiovascular disease mortality contributed about half of the widening relative gap for total mortality. Other causes also made important contributions to the widening gap in total mortality. For these causes, widening inequalities were sometimes due to increasing mortality rates in the lower socioeconomic groups. We found rising rates of mortality from lung cancer, breast cancer, respiratory disease, gastrointestinal disease, and injuries among men and/or women in lower socioeconomic groups in several countries. Reducing socioeconomic inequalities in mortality in Western Europe critically depends upon speeding up mortality declines from cardiovascular diseases in lower socioeconomic groups, and countering mortality increases from several other causes of death in lower socioeconomic groups.

Interaction of maternal protein and carbon monoxide on pup mortality in mice: implications for global infant mortality.

The United States Surgeon General declared 2005 as the "Year of Healthy Child." To improve the health of all children, we need to start before pregnancy, with their mothers. Unfortunately, protein deficiency in the diets of poor pregnant mothers in developing countries is widespread. Carbon monoxide (CO) pollution is serious public health problem in developed and developing countries. A two-way factorial experimental design was used. Mice were maintained on 27%, 16%, 8%, or 4% protein diets. Dams were exposed to 0 ppm (control), 65 ppm, or 125 ppm CO in air, in environmental chambers for 6 hr/day during the first 2 weeks of pregnancy. Controls were also subjected to environmental chamber conditions. Food and water were available at all times. Animals were allowed to deliver, and data on pup mortality was recorded. Litter size was not affected by CO exposure, but was directly related to the dietary protein levels. Pup weight was inversely related to the CO exposure level, and directly related to the dietary protein levels. Pup mortality on date of birth was increased by CO exposure and was inversely related to the dietary protein levels. Pup mortality at 1 week of age was increased by CO exposure and 55% of all pups died in 125 ppm CO exposed group. Pup mortality at 1 week of age was inversely related to dietary protein levels. All pups in the 4% dietary protein and in all concentrations of CO died. All pups in the 8% protein group and in all CO concentrations died except in 125 ppm CO group. Pup mortality in the 16% dietary protein group ranged from 14.8% in 0 ppm to 36.8% in 65 ppm CO groups. Pup mortality in the 27% dietary protein group ranged from 14.3% in the 0 ppm to 41.1% in the 125 ppm CO groups. DATA suggest that protein deficiency and CO exposure enhance pup mortality. The protein and CO also interact to increase pup mortality in 16% and 27% protein groups. Carbon monoxide exposure, along with protein deficiency during gestation, may be contributing factors for high rates of infant mortality in developing countries. The results of the study also suggest that un-vented combustion for heating and cooking, ambient pollution, and biomass smoke may have a major impact on the health of children worldwide; and may explain the causes of high infant mortality in poor countries and some sections of the United States population.

Using estimates from the 2013 Global Burden of Disease (GBD) study, we update evidence on disparities in under-five child injury mortality between developing and developed countries from 1990 to 2013. Mortality rates were accessed through the online visualization tool by the GBD study 2013 group. We calculated percent change in child injury mortality rates between 1990 and 2013. Data analysis was conducted separately for <1 year and 1-4 years to specify age differences in rate changes. Between 1990 and 2013, over 3-fold mortality gaps were observed between developing countries and developed countries for both age groups in the study time period. Similar decreases in injury rates were observed for developed and developing countries (<1 year: -50% vs. -50% respectively; 1-4 years: -56% vs. -58%). Differences in injury mortality changes during 1990-2013 between developing and developed nations varied with injury cause. There were greater reductions in mortality from transport injury, falls, poisoning, adverse effects of medical treatment, exposure to forces of nature, and collective violence and legal intervention in developed countries, whereas there were larger decreases in mortality from drowning, exposure to mechanical forces, and animal contact in developing countries. Country-specific analysis showed large variations across countries for both injury mortality and changes in injury mortality between 1990 and 2013. Sustained higher child injury mortality during 1990-2013 for developing countries merits the attention of the global injury prevention community. Countries that have high injury mortality can benefit from the success of other countries.

To determine the lunar effect on mortality among patients admitted to the intensive care unit. The retrospective study conducted at Rosalind Franklin University of Medicine and Science, North Chicago, and comprised data of 4387 patients in intensive care unit from December 2002 to November 2004. The subjects were divided into two groups: patients who died on full moon days (the 14th, 15th, and 16th days of the lunar month); and patients who died on the other days of the month. The mortality rates were calculated for patients in both groups. Parameters including patients' age, gender, acute physiology and chronic health evaluation scores, predicted mortality rates, type of intensive care unit, and actual mortality were compared, and non-parametric tests were performed to determine whether there were any differences between the groups. Of the 4387 patients who were followed for 23 months, 297 patients died, including 31 on full moon days and 266 patients on the other days of the month. Both groups were similar in terms of mean age (73.6 +/- 14.59 vs. 71.07 +/- 16.13 years; p = 0.599), acute physiology and chronic health evalutation scores (82.06 +/- 24.19 vs. 76.52 +/- 27.42; p = 0.258), and predicted mortality (0.405 +/- 0.249 vs. 0.370 +/- 0.268; p = 0.305). There was no difference in the frequency of death between the full moon days and the other days (10.33 +/- 0.58 vs. 9.8 +/- 3.46; p = 0.845). The full moon does not affect the mortality of the patients in intensive care unit.

To investigate the effect of general or regional anesthesia on postoperative cardiopulmonary complications and inpatient mortality after hip fracture surgery in elderly patients. A retrospective analysis was conducted according to the medical records of 572 elderly patients with hip fractures admitted to our hospital from January 1, 2005 to December 31, 2014. The age, gender, preoperative comorbidities, length of preoperative bedridden time, mechanism of injury, surgical types, anesthetic methods, major postoperative complications and inpatient mortality were recorded. Multivariate Logistic regression analysis was applied to analyze the impact of different anesthetic methods on inpatient mortality in these patients. Of the 572 patients, 392 (68.5%) received regional anesthesia. Inpatient death occurred in 8 (8/572, mortality: 1.4%), including 5 cases of RA group (5/392, mortality: 1.3%) and 3 cases of GA group (3/180, mortality: 1.7%). There was no statistically significant difference between the two groups in inpatient mortality (P>0.05). Multiple Logistic regression analysis showed that gender (odds ratio: 0.18, 95% CI: 0.03-1.05, P=0.057), age (odds ratio: 1.22, 95% CI: 1.07-1.38, P=0.002), preoperative pulmonary comorbidities (odds ratio: 12.09, 95% CI: 2.28-64.12, P=0.003) and surgical types (odds ratio: 9.36, 95% CI: 1.34-64.26, P=0.024) were risk factors for inpatient mortality. Postoperative cardiovascular complications occurred in 36 patients (36/572, morbidity: 6.3%), with 19 patients in RA group (19/392, morbidity: 4.8%),and 17 patients in GA group (17/180, morbidity: 9.4%). Multiple Logistic regression analysis showed that age (odds ratio: 1.13, 95% CI: 1.07-1.19, P<0.001), hypertension (odds ratio: 2.72, 95% CI: 1.24-5.96, P=0.012) and preoperative cerebral comorbidities (odds ratio: 2.11, 95% CI: 0.99-4.52, P=0.054) were risk factors for postoperative cardiovascular complications. Postoperative pulmonary complications occurred in 56 patients (56/572, morbidity: 9.8%), with 19 patients in RA group (19/392, morbidity: 4.8%), and 37 patients in GA group (37/180, morbidity: 20.6%). Multiple Logistic regression analysis showed that age (odds ratio: 1.13, 95% CI: 1.07-1.19, P<0.001), preoperative pulmonary comorbidities (odds ratio: 2.89, 95% CI: 1.28-7.05, P=0.020), length of preoperative bedridden time (odds ratio: 1.11, 95% CI: 1.04-1.18, P=0.003) and anesthetic methods (odds ratio: 5.86, 95% CI: 2.98-11.53, P<0.001) were risk factors for postoperative pulmonary complications. General anesthesia may not affect the inpatient mortality after hip fracture surgery in elderly patients. Regional anesthesia is associated with a lower risk of pulmonary complications after surgical procedure compared with general anesthesia.

The objective of this study was to analyze mortality due to the main external causes of death (traffic accidents, other accidents, homicides and suicides) in Mexico, calculating the years of life lost between 0 and 100 years of age and their contribution to the change in life expectancy between 2000 and 2013, at the national level, by sex and age group. Data came from mortality vital statistics of the Instituto Nacional de Estadística y Geografía (INEGI) [National Institute of Statistics and Geography]. The biggest impact in mortality due to external causes occurred in adolescent and adult males 15-49 years of age; mortality due to these causes remained constant in males and slightly decreased in females. Mortality due to traffic accidents and other accidents decreased, with a positive contribution to life expectancy, but this effect was canceled out by the increase in mortality due to homicides and suicides. Mortality due to external causes can be avoided through interventions, programs and prevention strategies as well as timely treatment. It is necessary to develop multidisciplinary studies on the dynamics of the factors associated with mortality due to these causes.

The aim of this descriptive epidemiological study was to analyze the mortality trend of prostate cancer in Serbia (excluding the Kosovo and Metohia) from 1991 to 2010. The age-standardized prostate cancer mortality rates (per 100 000) were calculated by direct standardization, using the World Standard Population. Average annual percentage of change (AAPC) and the corresponding 95% confidence interval (CI) was computed for trend using the joinpoint regression analysis. Significantly increased trend in prostate cancer mortality was recorded in Serbia continuously from 1991 to 2010 (AAPC = +2.2, 95% CI = 1.6-2.9). Mortality rates for prostate cancer showed a significant upward trend in all men aged 50 and over: AAPC (95% CI) was +1.9% (0.1-3.8) in aged 50-59 years, +1.7% (0.9-2.6) in aged 60-69 years, +2.0% (1.2-2.9) in aged 70-79 years and +3.5% (2.4-4.6) in aged 80 years and over. According to comparability test, prostate cancer mortality trends in majority of age groups were parallel (final selected model failed to reject parallelism, P > 0.05). The increasing prostate cancer mortality trend implies the need for more effective measures of prevention, screening and early diagnosis, as well as prostate cancer treatment in Serbia. © The Author 2015.

To analyze the temperature modification effect on acute mortality due to particulate air pollution. Daily non-accidental mortality, cardiovascular mortality, and respiratory mortality data were obtained from Jiang'an District Center for Disease Control and Prevention. Daily meteorological data on mean temperature and relative humidity were collected from China Meteorological Data Sharing Service System. The daily concentration of particulate matter was collected from Wuhan Environmental Monitoring center. By using the stratified time-series models, we analyzed effects of particulate air pollution on mortality under different temperature zone from 2002 to 2010, meanwhile comparing the difference of age, gender and educational level, in Wuhan city of China. High temperature (daily average temperature > 33.4 ℃) obviously enhanced the effect of PM10 on mortality. With 10 μg/m(3) increase in PM10 concentrations, non-accidental, cardiovascular, and respiratory mortality increased 2.95% (95%CI: 1.68%-4.24%), 3.58% (95%CI: 1.72%-5.49%), and 5.07% (95%CI: 2.03%-9.51%) respectively. However, low temperature (daily average temperature <-0.21 ℃) enhanced PM10 effect on respiratory mortality with 3.31% (95% CI: 0.07%-6.64%) increase. At high temperature, PM10 had significantly stronger effect on non-accidental mortality of female aged over 65 and people with high educational level groups. With an increase of 10 μg/m(3), daily non-accidental mortality increased 4.27% (95% CI:2.45%-6.12%), 3.38% (95% CI:1.93%-4.86%) and 3.47% (95% CI:1.79%-5.18%), respectively. Whereas people with low educational level were more susceptible to low temperature. A 10 μg/m(3) increase in PM10 was associated with 2.11% (95% CI: 0.20%-4.04%) for non-accidental mortality. Temperature factor can modify the association between the PM10 level and cause-specific mortality. Moreover, the differences were apparent after considering the age, gender and education groups.

Objective: To assess the disease burden attributable to household air pollution in 1990 and 2013 in China. Methods: Based on data from the Global Burden of Disease Study 2013 in China (GBD 2013), we used population attributable fractions (PAF) to analyze the burden of different diseases attributable to solid-fuel household pollution in 2013 in China(not inclnding HongKang, Macao, Taiwan). We compared PAF, mortality, and disability-adjusted life years (DALY) for diseases attributable to solid-fuel household pollution in 31 provinces in mainland China in 1990 and 2013, and stratified the burden by age group. The estimated world average population during 2000- 2025 was used to calculate age-standardized mortality and DALY rates. Results: In 2013, 14.9% of lower respiratory infections in children <5, 32.5% of chronic obstructive pulmonary disease (COPD), 12.0% of ischemic stroke, 14.2% of hemorrhagic stroke, 10.9% of ischemic heart disease, and 13.7% of lung cancer were attributable to solid-fuel household pollution. In addition, 807 000 deaths were attributable to solid-fuel household pollution, including 296 000 from COPD, 169 000 from hemorrhagic stroke, 152 000 from ischemic heart disease, 88 000 from ischemic stroke, 75 000 from lung cancer, and 28 000 from lower respiratory infections in children <5. The age-standardized mortality rate from solid-fuel household pollution decreased by 59.3% from 158.8/100 000 in 1990 to 64.6/100 000 in 2013. The age-standardized mortality rate from solid-fuel household pollution decreased in all 31 provinces, with the highest decline observed in Shanghai (96.3%), and lowest in Xinjiang (39.9%). In 2013, the age-standardized DALY rate from solid-fuel household pollution was highest in Guizhou (2 233.0/100 000) and lowest in Shanghai (27.0/100 000). The DALY rate was the highest for the >70 age group (7 006.0/100 000). Compared with 1990, the 2013 mortality rate and DALY rate from solid-fuel household pollution decreased in all age groups, with the highest decline observed in the <5 age group (91.9% and 91.8% , respectively). Conclusion: Although the disease burden attributable to household air pollution decreased notably between 1990 and 2013, household pollution caused a high number of deaths and DALY loss in certain western provinces.

Suicides are one of the main public health issues globally. Objective: To analyze the trends and impact of suicide mortality in Colombia and México between 2000 and 2013, nationally, by sex and age groups. Materials and methods: Mortality vital statistics from the Colombian Departamento Administrativo Nacional de Estadística and the Mexican Instituto Nacional de Estadística y Geografía were used. We conducted a descriptive and cross sectional study for which we calculated standardized mortality rates and years of life lost in people between 0 and 100 years of age. Results: In Colombia, the suicide mortality rate decreased between 2000 and 2013 for both sexes (28% for men and 38% for women); an opposite trend was observed in México (with an increase of 34% for males and 67% for females). In 2013, the years of life lost in Colombia were 0,32 among men and 0,15 among women, with a decreasing trend since 2000, whereas in México a level of 0,42 was observed in men and 0,2 in women, with an increasing trend since 2000. The age groups where suicides had a bigger impact were those of men 15 to 49 years of age in both countries, while suicides were more uniformly distributed among women between 15 and 84 years of age.  Suicide mortality increased gradually in México, whereas in Colombia an opposite trend was observed. Suicides can be prevented, so it is fundamental to implement public health policies focused on timely identification, comprehensive prevention strategies and the study of associated risk factors.

Cancer has become a major health problem associated with high mortality worldwide, especially in developing countries. The aim of our study was to evaluate the incidence rates of different types of cancer in Sulaymaniyah from January-2006 to January-2014. The data were compared with those reported for other middle east countries. This retrospective study depended on data collected from Hiwa hospital cancer registry unit, death records and histopathology reports in all Sulaymaniyah teaching hospitals, using international classification of diseases. A total of 8,031 cases were registered during the eight year period, the annual incidence rate in all age groups rose from 38 to 61.7 cases/100,000 population/year, with averages over 50 in males and 50.7 in females. The male to female ratio in all age groups were 0.98, while in the pediatric age group it was 1.33. The hematological malignancies in all age groups accounted for 20% but in the pediatric group around half of all cancer cases. Pediatric cancers were occluding 7% of total cancers with rates of 10.3 in boys and 8.7 in girls. The commonest malignancies by primary site were leukemia, lymphoma, brain, kidney and bone. In males in all age groups they were lung, leukaemia, lymphoma, colorectal, prostate, bladder, brain, stomach, carcinoma of unknown primary (CUP) and skin, while in females they were breast, leukaemia, lymphoma, colorectal, ovary, lung, brain, CUP, and stomach. Most cancers were increased with increasing age except breast cancer where decrease was noted in older ages. High mortality rates were found with leukemia, lung, lymphoma, colorectal, breast and stomach cancers. We here found an increase in annual cancer incidence rates across the period of study, because of increase of cancer with age and higher rates of hematological malignancies. Our study is valuable for Kurdistan and Iraq because it provides more accurate data about the exact patterns of cancer and mortality in our region.

Background Many studies have established a link between weather (primarily temperature) and daily mortality in developed countries. However, little is known about this relationship in urban populations in sub-Saharan Africa. Objectives The objective of this study was to describe the relationship between daily weather and mortality in Nairobi, Kenya, and to evaluate this relationship with regard to cause of death, age, and sex. Methods We utilized mortality data from the Nairobi Urban Health and Demographic Surveillance System and applied time-series models to study the relationship between daily weather and mortality for a population of approximately 60,000 during the period 2003–2008. We used a distributed lag approach to model the delayed effect of weather on mortality, stratified by cause of death, age, and sex. Results Increasing temperatures (above 75th percentile) were significantly associated with mortality in children and non-communicable disease (NCD) deaths. We found all-cause mortality of shorter lag of same day and previous day to increase by 3.0% for a 1 degree decrease from the 25th percentile of 18°C (not statistically significant). Mortality among people aged 50+ and children aged below 5 years appeared most susceptible to cold compared to other age groups. Rainfall, in the lag period of 0–29 days, increased all-cause mortality in general, but was found strongest related to mortality among females. Low temperatures were associated with deaths due to acute infections, whereas rainfall was associated with all-cause pneumonia and NCD deaths. Conclusions Increases in mortality were associated with both hot and cold weather as well as rainfall in Nairobi, but the relationship differed with regard to age, sex, and cause of death. Our findings indicate that weather-related mortality is a public health concern for the population in the informal settlements of Nairobi, Kenya, especially if current trends in climate change continue.

This study analyzes firearms mortality (FA) and their impact on life expectancy in Mexico -compared to other causes of deaths- during the three-year periods 2000-2002 and 2010-2012 and the weight of the different age groups in years of life expectancy lost (YLEL) due to this cause. Based on official death and population data, abridged life tables in Mexico were constructed for the three-year periods studied. Temporary life expectancy and YLEL for aged 15 to 75 by selected causes and age groups were calculated in each three-year period. Among men, FA mortality went from being the cause less YLEL caused in 2000-2002 to be the main cause of YLEL between 15 and 75 years in 2010-2012. Among women, YLEL for FA mortality had a higher relative growth. In both sexes, the greatest increase in YLEL by FA mortality was between 20 and 34 years. Findings indicate that the increase in FA mortality, especially among young people, has substantially contributed to the stagnation of life expectancy in recent years, and even his decline in the case of men. This reflects that violence linked to the FA is not only a security problem but also a collective health problem that must be copied in an interdisciplinary and intersectoral form if it is to increase the life expectancy of the country.

Pancreatic (PC) and biliary tract (BTC) cancers have higher incidence and mortality in Europe than elsewhere. We analysed time-trends in PC/BTC incidence, mortality, and survival across Europe. Since the European standard population (ESP) was recently revised to better represent European age structure, we also assessed the effect of adopting the revised ESP to age-standardise incidence and mortality data. We analysed PCs/BTCs (≥15 years) diagnosed in 2000-2007 and followed-up to end of 2008, in 29 European countries across five regions: UK/Ireland, and northern, central, southern, and eastern Europe. Incidence, mortality, and 5-year relative survival were compared between regions, by age, sex, and period of diagnosis. Variation in age-standardised incidence (PC 12-15/100,000; BTC 2-6) and mortality (PC 10-14; BTC 1-5) was modest. Eastern Europe had highest incidence and mortality, and lowest survival; northern and southern Europe had highest age-specific incidence (most age groups) for PC and BTC, respectively. Incidence and survival increased slightly from 2000 to 2007, particularly in elderly patients and women, but survival remained poor (≤8% for PC; 13-18% for BTC). Use of the revised ESP for age-standardisation did not impact European regional incidence and mortality rankings. Poor survival for PC and BTC, together with increasing incidence, indicate that action is required. Countries with higher incidence had higher risk factor frequency, suggesting that prevention initiatives targeting risk factors should be promoted. Improvements in diagnosis and treatment are also required. Our results provide a baseline from which to monitor evolution of the PC/BTC burden in Europe. Copyright © 2018 Elsevier Ltd.

Using historical data from 1,763 birth cohorts from 1800 to 1935 in 13 developed countries, we show that what is now seen as normal—a large excess of female life expectancy in adulthood—is a demographic phenomenon that emerged among people born in the late 1800s. We show that excess adult male mortality is clearly rooted in specific age groups, 50–70, and that the sex asymmetry emerged in cohorts born after 1880 when male:female mortality ratios increased by as much as 50% from a baseline of about 1.1. Heart disease is the main condition associated with increased excess male mortality for those born after 1900. We further show that smoking-attributable deaths account for about 30% of excess male mortality at ages 50–70 for cohorts born in 1900–1935. However, after accounting for smoking, substantial excess male mortality at ages 50–70 remained, particularly from cardiovascular disease. The greater male vulnerability to cardiovascular conditions emerged with the reduction in infectious mortality and changes in health-related behaviors. PMID:26150507

Background Little is known about the effects of intermittent preventive treatment of malaria in pregnancy (IPTp) on the health of sub-Saharan African infants. We have evaluated the safety of IPTp with mefloquine (MQ) compared to sulfadoxine-pyrimethamine (SP) for important infant health and developmental outcomes. Methods and Findings In the context of a multicenter randomized controlled trial evaluating the safety and efficacy of IPTp with MQ compared to SP in pregnancy carried out in four sub-Saharan countries (Mozambique, Benin, Gabon, and Tanzania), 4,247 newborns, 2,815 born to women who received MQ and 1,432 born to women who received SP for IPTp, were followed up until 12 mo of age. Anthropometric parameters and psychomotor development were assessed at 1, 9, and 12 mo of age, and the incidence of malaria, anemia, hospital admissions, outpatient visits, and mortality were determined until 12 mo of age. No significant differences were found in the proportion of infants with stunting, underweight, wasting, and severe acute malnutrition at 1, 9, and 12 mo of age between infants born to women who were on IPTp with MQ versus SP. Except for three items evaluated at 9 mo of age, no significant differences were observed in the psychomotor development milestones assessed. Incidence of malaria, anemia, hospital admissions, outpatient visits, and mortality were similar between the two groups. Information on the outcomes at 12 mo of age was unavailable in 26% of the infants, 761 (27%) from the MQ group and 377 (26%) from the SP group. Reasons for not completing the study were death (4% of total study population), study withdrawal (6%), migration (8%), and loss to follow-up (9%). Conclusions No significant differences were found between IPTp with MQ and SP administered in pregnancy on infant mortality, morbidity, and nutritional outcomes. The poorer performance on certain psychomotor development milestones at 9 mo of age in children born to women in the MQ group compared to those in the SP group may deserve further studies.

Previous studies in several countries have shown that the economically disadvantaged seem to have a greater risk of being involved in a car crash. The aim of the present study was to compare rates and trends in mortality and injury from road crashes by age among the Arab and Jewish populations in Israel. Data on road crashes with casualties (2003-2011) from the Israeli Central Bureau of Statistics were analyzed. Age-adjusted road crash injury rates and mortality rates for 2003 to 2011 were calculated and time trends for each age group and population group are presented. Time trend significance was evaluated by linear regression models. Arabs in Israel are at increased risk of injury and mortality from road crashes compared to Jews. Road crash injury rates have significantly decreased in both populations over the last decade, although the rates have been persistently higher among Arabs. Road crash mortality rates have also decreased significantly in the Jewish population but not in the Arab population. This implies an increase in the disparity in mortality between Jews and Arabs. The most prominent differences in road crash injury and mortality rates between Arabs and Jews can be observed in young adults and young children. The reduction in road crashes in the last decade is a positive achievement. However, the reductions are not equal among Arabs and Jews in Israel. Therefore, an increase in the disparities in mortality from road crashes is apparent. Public health efforts need to focus specifically on decreasing road crashes in the Arab community.

to provide up-to-date information and to analyze recent changes in colorectal cancer mortality trends in Andalusia during the period of 1980-2008 using joinpoint regression models. age- and sex-specific colorectal cancer deaths were taken from the official vital statistics published by the Instituto de Estadística de Andalucía for the years 1980 to 2008. We computed age-specific rates for each 5-year age group and calendar year and age-standardized mortality rates per 100,000 men and women. A joinpoint regression analysis was used for trend analysis of standardized rates. Joinpoint regression analysis was used to identify the years when a significant change in the linear slope of the temporal trend occurred. The best fitting points (the "join-points") are chosen where the rate significantly changes. mortality from colorectal cancer in Andalusia during the period studied has increased, from 277 deaths in 1980 to 1,227 in 2008 in men, and from 333 to 805 deaths in women. Adjusted overall colorectal cancer mortality rates increased from 7.7 to 17.0 deaths per 100,000 person-years in men and from 6.6 to 9.0 per 100,000 person-years in women Changes in mortality did not evolve similarly for men and women. Age-specific CRC mortality rates are lower in women than in men, which imply that women reach comparable levels of colorectal cancer mortality at higher ages than men. sex differences for colorectal cancer mortality have been widening in the last decade in Andalusia. In spite of the decreasing trends in age-adjusted mortality rates in women, incidence rates and the absolute numbers of deaths are still increasing, largely because of the aging of the population. Consequently, colorectal cancer still has a large impact on health care services, and this impact will continue to increase for many more years.

Aging plays an essential role in cardiac pathophysiology. Knowledge on the ventricular repolarization in very old individuals is limited. An increase of QT dispersion is associated with higher cardiovascular mortality. The purpose of this study is to investigate whether aging changes the QT dispersion in the very old. Heart rate, P wave duration, PR interval, QRS axis, QRS duration, QT interval, and QTc interval were measured from 12-lead resting ECG. QT dispersion (46 ± 21, 47 ± 17, 69 ± 31 ms, p < 0.005) was significantly increased in the age group ≧85 years (n = 29, 89 ± 4 years) than in the age group 75-84 years (n = 33, 79 ± 3 years) and the age group 65-74 years (n = 32, 68 ± 3 years). Aging modulates dispersion of ventricular repolarization, which may contribute to the cardiac mortality in the very old Asian population.

Mortality associated with bilirubin levels in insurance applicants.

Determine the relationship between bilirubin levels with and without other liver function test (LFT) elevations and relative mortality in life insurance applicants. By use of the Social Security Death Master File mortality was determined in 1,905,664 insurance applicants for whom blood samples were submitted to the Clinical Reference Laboratory. There were 50,174 deaths observed in this study population. Results were stratified by 3 age/sex groups: females, age <60; males, age <60; and all, age 60+. The median follow-up was 12 years. Relative mortality increased as bilirubin decreased below bilirubin levels seen for the middle 50% of the population. The known association of smoking with lower bilirubin values explained only part of the additional elevated risk at low bilirubin levels. In the absence of other LFT elevations, relative mortality remained unchanged as bilirubin increased beyond levels seen for the middle 50% of the population. When a bilirubin elevation was combined with other LFT elevations, mortality further increased only at the highest elevations of other LFTs, seen only in <2.5% of applicants. Isolated elevations of bilirubin in this healthy screening population were not associated with excess mortality but values below the midpoint were. Other investigations have suggested a cardiovascular cause may underlie the excess mortality associated with low bilirubin. In association with other LFT elevations, bilirubin elevation further increases the mortality risk only at the highest elevations of other LFTs.

We assess the extent to which differences in socio-economic status are associated with racial and ethnic gaps in a fundamental measure of population health: the rate at which infants die. Using micro-level Vital Statistics data from 2000 to 2004, we examine mortality gaps of infants born to white, black, Mexican, Puerto Rican, Asian, and Native American mothers. We find that between-group mortality gaps are strongly and consistently (except for Mexican infants) associated with maternal marital status, education, and age, and that these same characteristics are powerful predictors of income and poverty for new mothers in U.S. Census data. Despite these similarities, we document a fundamental difference in the mortality gap for the three high mortality groups: whereas the black-white and Puerto Rican-white mortality gaps mainly occur at low birth weights, the Native American-white gap occurs almost exclusively at higher birth weights. We further examine the one group whose IMR is anomalous compared to the other groups: infants of Mexican mothers die at relatively low rates given their socio-economic disadvantage. We find that this anomaly is driven by lower infant mortality among foreign-born mothers, a pattern found within many racial/ethnic groups. Overall, we conclude that the infant mortality gaps for our six racial/ethnic groups exhibit many commonalities, and these commonalities suggest a prominent role for socio-economic differences.

Elderly patients often remain underrepresented in clinical trials. The aim of our study was to analyze the treatment, clinical outcome and risk factors for mortality in patients aged ≥85 years with ST-segment elevation myocardial infarction (STEMI). From 2005-2011, 102 patients aged ≥85 years with STEMI admitted to a coronary care unit were retrospectively reviewed. Clinical data, treatment and outcome were recorded. Reperfusion strategy and its influence in hospital morbidity and mortality were evaluated. Morbidity was defined as the presence of heart failure (Killip-Kimball >1), arrhythmias, mechanical complications, stroke or major bleeding. Risk factors for mortality were assessed by multivariate analysis. The mean age was 87.5±2.5 years (range 85-96). Therapeutic strategy on admission was: primary-angioplasty (PCI) for 33 patients (32.3%) fibrinolysis for 30 patients (29.4%) and conservative treatment for 35 patients (34.3%). In the four remaining patients, rescue angioplasty was required. A total of 29 patients (28.4%) died, and morbidity was seen in 63 patients (61.7%). The morbidity and mortality rates in the conservative treatment group (77.1% and 48.5%) were higher than that found in the reperfusion strategy group (primary-PCI and fibrinolysis; 53.7% and 17.9%; P=0.02 and P=0.002, respectively). Regarding mortality, the univariate analysis showed that heart failure on admission (P=0.0001) and previous coronary artery disease (P=0.01) were prognostic variables. Only heart failure was an independent risk factor for mortality (odds ratio=3.64, 95% CI 0.78-21.87, P<0.0001). Mortality and morbidity in very elderly patients with STEMI are very high, especially in those not receiving reperfusion therapies. Heart failure on admission was an independent risk factor for hospital mortality. © 2012 Japan Geriatrics Society.

Psychosocial stress contributes to high blood pressure and subsequent cardiovascular morbidity and mortality. Previous controlled studies have associated decreasing stress with the Transcendental Meditation (TM) program with lower blood pressure. The objective of the present study was to evaluate, over the long term, all-cause and cause-specific mortality in older subjects who had high blood pressure and who participated in randomized controlled trials that included the TM program and other behavioral stress-decreasing interventions. Patient data were pooled from 2 published randomized controlled trials that compared TM, other behavioral interventions, and usual therapy for high blood pressure. There were 202 subjects, including 77 whites (mean age 81 years) and 125 African-American (mean age 66 years) men and women. In these studies, average baseline blood pressure was in the prehypertensive or stage I hypertension range. Follow-up of vital status and cause of death over a maximum of 18.8 years was determined from the National Death Index. Survival analysis was used to compare intervention groups on mortality rates after adjusting for study location. Mean follow-up was 7.6 ± 3.5 years. Compared with combined controls, the TM group showed a 23% decrease in the primary outcome of all-cause mortality after maximum follow-up (relative risk 0.77, p = 0.039). Secondary analyses showed a 30% decrease in the rate of cardiovascular mortality (relative risk 0.70, p = 0.045) and a 49% decrease in the rate of mortality due to cancer (relative risk 0.49, p = 0.16) in the TM group compared with combined controls. These results suggest that a specific stress-decreasing approach used in the prevention and control of high blood pressure, such as the TM program, may contribute to decreased mortality from all causes and cardiovascular disease in older subjects who have systemic hypertension.

Investigations into socioeconomic inequalities in mortality have rarely used long-term mortality follow-up data from nationally representative samples in Asian countries. A limited subset of indicators for socioeconomic position was employed in prior studies on socioeconomic inequalities in mortality. We examined socioeconomic inequalities in mortality using follow-up 12-year mortality data from nationally representative samples of South Koreans. A total of 10,137 individuals who took part in the 1998 and 2001 Korea National Health and Nutrition Examination Surveys were linked to mortality data from Statistics Korea. Of those individuals, 1,219 (12.1 %) had died as of December 2012. Cox proportional hazard models were used to estimate the relative risks of mortality according to a wide range of socioeconomic position (SEP) indicators after taking into account primary sampling units, stratification, and sample weights. Our analysis showed strong evidence that individuals with disadvantaged SEP indicators had greater all-cause mortality risks than their counterparts. The magnitude of the association varied according to gender, age group, and specific SEP indicators. Cause-specific analyses using equivalized income quintiles showed that the magnitude of mortality inequalities tended to be greater for cardiovascular disease and external causes than for cancer. Inequalities in mortality exist in every aspect of SEP indicators, both genders, and age groups, and four broad causes of deaths. The South Korean economic development, previously described as effective in both economic growth and relatively equitable income distribution, should be scrutinized regarding its impact on socioeconomic mortality inequalities. Policy measures to reduce inequalities in mortality should be implemented in South Korea.

Maternal mortality in Mexico, beyond millennial development objectives: An age-period-cohort model.

The maternal mortality situation is analyzed in México as an indicator that reflects the social development level of the country and was one of the millennial development objectives. The effect of a maternal death in the related social group has multiplier effects, since it involves family dislocation, economic impact and disruption of the orphans' normal social development. Two perspectives that causes of maternal mortality were analyzed, on one hand, their relationship with social determinants and on the other, factors directly related to the health system. Evidence shows that comparing populations based on group of selected variables according to social conditions and health care access, statistically significant differences prevail according to education and marginalization levels, and access to medical care. In addition, the Age-Period-Cohort model raised, shows significant progress in terms of a downward trend in maternal mortality in a generational level. Those women born before 1980 had a greater probability of maternal death in relation to recent generations, which is a reflection of the improvement in social determinants and in the Health System. The age effect shows a problem in maternal mortality in women under 15 years old, so teen pregnancy is a priority in health and must be addressed in short term. There is no clear evidence of a period effect.

Prevention of disability is a major challenge in aging populations; however, the extent to which physical independence can be maintained toward the limit of human life span remains to be determined. We examined the health and functional status of 642 centenarians: 207 younger centenarians (age: 100-104 years), 351 semi-supercentenarians (age: 105-109 years), and 84 supercentenarians (age: >110 years). All-cause mortality was followed by means of an annual telephone or mailed survey. Age-specific disability patterns revealed that the older the age group, the higher the proportion of those manifesting independence in activities of daily living at any given age of entry. Multiple logistic regression analysis identified male gender and better cognitive function as consistent determinants of physical independence across all age categories. In a longitudinal analysis, better physical function was significantly associated with survival advantage until the age of 110. However, mortality beyond that age was predicted neither by functional status nor biomedical measurements, indicating alternative trajectories of mortality at the highest ages. These findings suggest that maintaining physical independence is a key feature of survival into extreme old age. Future studies illuminating genetic and environmental underpinnings of supercentenarians' phenotypes will provide invaluable opportunities not only to improve preventive strategies but also to test the central hypotheses of human aging.

To assess and compare the predictive ability of three risk evaluation systems (SinoSCORE, EuroSCORE II and the STS risk evaluation system) in patients aged ≥70, and who underwent coronary artery bypass grafting (CABG) in East China. Three risk evaluation systems were applied to 1,946 consecutive patients who underwent isolated CABG from January 2004 to September 2016 in two hospitals. Patients were divided into two subsets according to their age: elderly group (age ≥70) with a younger group (age <70) used for comparison. The outcome of interest in this study was in-hospital mortality. The entire cohort and subsets of patients were analyzed. The calibration and discrimination in total and in subsets were assessed by the Hosmer-Lemeshow and the C statistics respectively. Institutional overall mortality was 2.52%. The expected mortality rates of SinoSCORE, EuroSCORE II and the STS risk evaluation system were 0.78(0.64)%, 1.43(1.14)% and 0.78(0.77)%, respectively. SinoSCORE achieved the best discrimination (the area under the receiver operating characteristic curve (AUC) = 0.829), followed by the STS risk evaluation system (AUC = 0.790) and EuroSCORE II (AUC = 0.769) in the entire cohort. In the elderly group, the observed mortality rate was 4.82% while it was 1.38% in the younger group. SinoSCORE (AUC = .829) also achieved the best discrimination in the elderly group, followed by the STS risk evaluation system (AUC = .730) and EuroSCORE II (AUC = 0.640) while all three risk evaluation systems all had good performances in the younger group. SinoSCORE, EuroSCORE II and the STS risk evaluation system all achieved positive calibrations in the entire cohort and subsets. The performance of the three risk evaluation systems was not ideal in the entire cohort. In the elderly group, SinoSCORE appeared to achieve better predictive efficiency than EuroSCORE II and the STS risk evaluation system.

Objective To compare all-cause and cause-specific mortality among 3 distinct groups: within-country, rural-to-urban migrants, and rural and urban dwellers in a longitudinal cohort in Peru. Methods The PERU MIGRANT Study, a longitudinal cohort study, used an age-stratified and sex-stratified random sample of urban dwellers in a shanty town community in the capital city of Peru, rural dwellers in the Andes, and migrants from the Andes to the shanty town community. Participants underwent a questionnaire and anthropomorphic measurements at a baseline evaluation in 2007–2008 and at a follow-up visit in 2012–2013. Mortality was determined by death certificate or family interview. Results Of the 989 participants evaluated at baseline, 928 (94%) were evaluated at follow-up (mean age 48 years; 53% female). The mean follow-up time was 5.1 years, totalling 4732.8 person-years. In a multivariable survival model, and relative to urban dwellers, rural participants had lower all-cause mortality (HR=0.27; 95% CI 0.07 to 0.98), and both the rural (HR=0.07; 95% CI 0.01 to 0.87) and migrant (HR=0.13; 95% CI 0.02 to 0.81) groups had lower cardiovascular mortality. Conclusions Cardiovascular mortality of migrants remains similar to that of the rural group, suggesting that rural-to-urban migrants do not appear to catch up with urban mortality in spite of having a more urban cardiovascular risk factor profile.

The ideal age for correction of tetralogy of Fallot is still under discussion. The aim of this study was to analyze morbidity and mortality in patients who underwent early primary repair of tetralogy of Fallot at the age of less than 4 months and to assess whether neonates, who needed early repair within the first 4 weeks of life, faced an increased risk. From 1995 to 2006, 90 consecutive patients with tetralogy of Fallot and pulmonary stenosis underwent early primary repair. Patient charts were analyzed retrospectively for two groups: group A, 25 neonates younger than 28 days who needed early operation owing to duct-dependent pulmonary circulation or severe hypoxemia; and group B, 65 infants younger than 4 months of age who underwent elective early repair. There was no 30-day mortality; late mortality was 2% after a median follow-up time of 4.7 years. Seven of 88 patients (8%) needed reoperation and twelve of 88 patients (14%) needed reintervention. Groups A and B did not differ significantly in terms of intensive care unit stay, days of mechanical ventilation, overall hospital stay, major or minor complications, or reoperation. Significant differences were found in a more frequent use of a transannular patch (p = 0.045) and more reinterventions (p = 0.046) in group A. Early primary repair of tetralogy of Fallot can be performed safely and effectively in infants younger than 4 months of age and even in neonates younger than 28 days with duct-dependent pulmonary circulation or severe hypoxemia.

To determine hospitalization durations and mortalities of elderly in the Cardiovascular Surgery Intensive Care Unit. The retrospective study was conducted in a Cardiovascular Surgery Intensive Care Unit in Turkey and comprised patient records from January 1 to December 31, 2011. Computerized epicrisis reports of 255, who had undergone a cardiac surgery were collected. The patients were grouped according to their ages, Group I aged 65-74 and Group II aged 75 and older. European society for Cardiac Operative Risk Evaluation scores of the two groups were compared using SPSS 17. Overall, there were 80 (31.37%) females and 175 (68.62%) males. There were 138 (54.1%) patients in Group I and 117 (45.9%) in Group II. Regarding their hospitalization reasons, it was determined that 70 (27.5%) patients in Group I and 79 (30.9%) patients in Group II were treated with the diagnosis ofcoronary artery disease. The average hospitalization duration of patients in the intensive care unit was determined to be 11.57 +/- 0.40 days. Regarding the EuroSCORE score intervals of patients, 132 (51.8%) had 3-5 and 225 (88.2%) patients were transferred to the Cardiovascular Surgery and then all of them were discharged; 5 (4.1%) had a mortal course; and 11 (7.7%) were transferred to the anaesthesia intensive care unit. The general mortality rates are very low in the Cardiovascular Surgery Intensive Care Unit and the patients have a good prognosis.

Country and global health statistics underestimate the number of excess deaths due to diabetes. The aim of the study was to provide a more accurate estimate of the number of deaths attributable to diabetes for the year 2010. A computerized disease model was used to obtain the estimates. The baseline input data included the population structure, estimates of diabetes prevalence, estimates of underlying mortality and estimates of the relative risk of death for people with diabetes compared to people without diabetes. The total number of excess deaths attributable to diabetes worldwide was estimated to be 3.96 million in the age group 20-79 years, 6.8% of global (all ages) mortality. Diabetes accounted for 6% of deaths in adults in the African Region, to 15.7% in the North American Region. Beyond 49 years of age diabetes constituted a higher proportion of deaths in females than in males in all regions, reaching over 25% in some regions and age groups. Thus, diabetes is a considerable cause of premature mortality, a situation that is likely to worsen, particularly in low and middle income countries as diabetes prevalence increases. Investments in primary and secondary prevention are urgently required to reduce this burden. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

The impact of hemorrhagic stroke (HS) on the mortality of cirrhotic patients is unknown. To evaluate the morality risk of HS in cirrhotic patients, we used the Taiwan National Health Insurance Database to evaluate cirrhotic patients with HS who were discharged between 1 January and 31 December 2007. In total, there were 321 cirrhotic patients with HS. We randomly selected 3210 cirrhotic patients without HS as a comparison group. The 30 and 90 day mortality rates were 29.6% and 43.0% in the HS group, and 9.1% and 17.7% in the comparison group, respectively (p<0.001). After Cox proportional hazard regression model adjustment of patients' sex, age, and other comorbid disorders, the hazard ratio (HR) for 90 day mortality in the HS group was 3.89 (95% confidence interval [CI] 3.20-4.71, p<0.001), compared to the comparison group. In the subgroup analysis, the HR for 90 day mortality in the subarachnoid hemorrhage and other HS groups were 7.93 (95% CI 5.23-12.0, p<0.001) and 3.51 (95% CI 2.85-4.32, p<0.001), respectively, compared to the comparison group. In conclusion, HS is associated with a very high 90 day mortality risk in cirrhotic patients, in whom subarachnoid hemorrhage can also increase the risk of mortality eight-fold.

Life expectancy is used to measure population health, but large differences in mortality can be masked even when there is no life expectancy gap. We demonstrate how Arriaga's decomposition method can be used to assess inequality in mortality between populations with near equal life expectancy. We calculated life expectancy at birth for Quebec and the rest of Canada from 2005 to 2009 using life tables and partitioned the gap between both populations into age and cause-specific components using Arriaga's method. The life expectancy gap between Quebec and Canada was negligible (<0.1 years). Decomposition of the gap showed that higher lung cancer mortality in Quebec was offset by cardiovascular mortality in the rest of Canada, resulting in identical life expectancy in both groups. Lung cancer in Quebec had a greater impact at early ages, whereas cardiovascular mortality in Canada had a greater impact at older ages. Despite the absence of a gap, we demonstrate using decomposition analyses how lung cancer at early ages lowered life expectancy in Quebec, whereas cardiovascular causes at older ages lowered life expectancy in Canada. We provide SAS/Stata code and an Excel spreadsheeet to facilitate application of Arriaga's method to other settings. Copyright © 2014 Elsevier Inc. All rights reserved.

Excess black mortality in the United States and in selected black and white high-poverty areas, 1980-2000.

2011-04-01

Black working-aged residents of urban high-poverty areas suffered severe excess mortality in 1980 and 1990. Our goal in this study was to determine whether this trend persisted in 2000. We analyzed death certificate and census data to estimate age-standardized all-cause and cause-specific mortality among 16- to 64-year-old Blacks and Whites nationwide and in selected urban and rural high-poverty areas. Urban men's mortality rate estimates peaked in 1990 and declined between 1990 and 2000 back to or below 1980 levels. Evidence of excess mortality declines among urban or rural women and among rural men was modest, with some increases. Between 1980 and 2000, there was little decline in chronic disease mortality among men and women in most areas, and in some instances there were increases. In 2000, despite improved economic conditions, working-age residents of the study areas still died disproportionately of early onset of chronic disease, suggesting an entrenched burden of disease and unmet health care needs. The lack of consistent improvement in death rates among working-age residents of high-poverty areas since 1980 necessitates reflection and concerted action given that sustainable progress has been elusive for this age group.

How to allocate limited vaccine supplies in the event of an influenza pandemic is currently under debate. Conventional vaccination strategies focus on those at highest risk for severe outcomes, including seniors, but do not consider (1) the signature pandemic pattern in which mortality risk is shifted to younger ages, (2) likely reduced vaccine response in seniors, and (3) differences in remaining years of life with age. We integrated these factors to project the age-specific years of life lost (YLL) and saved in a future pandemic, on the basis of mortality patterns from 3 historical pandemics, age-specific vaccine efficacy, and the 2000 US population structure. For a 1918-like scenario, the absolute mortality risk is highest in people <45 years old; in contrast, seniors (those >or=65 years old) have the highest mortality risk in the 1957 and 1968 scenarios. The greatest YLL savings would be achieved by targeting different age groups in each scenario; people <45 years old in the 1918 scenario, people 45-64 years old in the 1968 scenario, and people >45 years old in the 1957 scenario. Our findings shift the focus of pandemic vaccination strategies onto younger populations and illustrate the need for real-time surveillance of mortality patterns in a future pandemic. Flexible setting of vaccination priority is essential to minimize mortality.

Trends in Education-Specific Life Expectancy, Data Quality, and Shifting Education Distributions: A Note on Recent Research.

PubMed

Hendi, Arun S

2017-06-01

Several recent articles have reported conflicting conclusions about educational differences in life expectancy, and this is partly due to the use of unreliable data subject to a numerator-denominator bias previously reported as ranging from 20 % to 40 %. This article presents estimates of life expectancy and lifespan variation by education in the United States using more reliable data from the National Health Interview Survey. Contrary to prior conclusions in the literature, I find that life expectancy increased or stagnated since 1990 among all education-race-sex groups except for non-Hispanic white women with less than a high school education; there has been a robust increase in life expectancy among white high school graduates and a smaller increase among black female high school graduates; lifespan variation did not increase appreciably among high school graduates; and lifespan variation plays a very limited role in explaining educational gradients in mortality. I also discuss the key role that educational expansion may play in driving future changes in mortality gradients. Because of shifting education distributions, within an education-specific synthetic cohort, older age groups are less negatively selected than younger age groups. We could thus expect a greater concentration of mortality at younger ages among people with a high school education or less, which would be reflected in increasing lifespan variability for this group. Future studies of educational gradients in mortality should use more reliable data and should be mindful of the effects of shifting education distributions.

Epidemiology of traumatic spinal cord injuries in Austria 2002-2012.

The aim of this study was to analyse the epidemiological patterns (mortality, incidence of non-fatal cases and overall incidence), of traumatic spinal cord injuries (TSCI) in 2002-2012 in Austria. TSCI-related deaths and hospital admissions in Austria 2002-2012 were obtained from Statistics Austria and analysed. Mortality rates, as well as non-fatal and overall incidence rates were calculated and compared across the age spectrum and by sex. Additionally, the main causes and demographic characteristics of victims were analysed. The crude overall incidence rate of TSCI was 16.96, CI 95 % 16.95-16.97 and the standardized incidence rate was 13.98, CI 95 % 13.97-13.99 per million (annual average rate). An annual increase in fatality rates was observed occurring mostly in the age group >65 years (Kendall's Tau = 0.1). Falls (mortality rate 19.58, CI 95 % 19.57-19.59) and injuries at home (incidence rate 56.57, CI 95 % 56.56-56.58) were the principal causes of fatal and non-fatal TSCI, respectively. Injuries to the neck region were the most common. All indicators were the highest for the age group >65 years: non-fatal incidence rate 23.55, CI 95 % 23.54-23.56; mortality rate 21.4, CI 95 % 21.39-21.41; and overall incidence rate 47.9, CI 95 % 47.89-47.91. A clear male dominance was observed (incidence rate ratio 1.9, CI 95 % 1.4-2.7). The population >65 years has been at the highest risk of TSCI in Austria for the analysed period and therefore preventive activities should be focused on this group. The increasing overall incidence of TSCI was driven by the increasing mortality rates that were highest in the age group >65 years. We advocate harmonization of epidemiological reporting especially regarding aetiology of TSCI in order to better inform policy makers and prevention.

We aimed to see whether primary percutaneous coronary intervention (PCI) benefits for ST-segment elevation myocardial infarction (STEMI) in the aged could be validated. Primary PCI benefits in elderly patients with STEMI remain uncertain. We reviewed 947 consecutive patients treated with primary PCI for STEMI: 331 were aged ≥75 years (older) and 616 <75 years (younger). The older group had higher percentage of renal insufficiency (7.9% vs. 3.1%, P = 0.0010), prior stroke (9.4% vs. 3.9%, P = 0.0006), 30-day mortality rate (7.6% vs. 3.9%, P = 0.015), and cardiac mortality rate (6.6% vs. 3.7%, P = 0.045). Successful reperfusion rates were similarly high in both groups (90.0% and 92.7%, P = 0.16), despite the higher proportion of patients with door-to-balloon time >90 min (15% vs. 8.4%, P = 0.0016) in older patients. Successful compared with unsuccessful PCI significantly decreased 30-day mortality rates in the older group (6.0% vs. 21%, P = 0.0018) and in the younger group (2.8% vs. 18%, P < 0.0001). When reperfusion was successful, cardiac mortality rate in older patients was not significantly greater than in younger patients (5.4% vs. 2.8%, P = 0.057). By multivariate analysis, unsuccessful reperfusion independently predicted 30-day mortality (odds ratio, 4.04; 95% confidence interval, 1.79-9.12; P = 0.0008), whereas age ≥75 years (odds ratio, 1.00; 95% confidence interval, 0.41-2.41; P = 0.99) and door-to-balloon time >90 min (odds ratio, 1.78; 95% confidence interval, 0.76-4.20; P = 0.19) did not. Pre-existing comorbidities characterize older patients developing STEMI. Aggressive PCI in older patients improves prognosis, and short door-to-balloon time is an important parameter conditioning the prognosis. Copyright © 2011 Wiley Periodicals, Inc.

Increased risk of death immediately after losing a spouse: Cause-specific mortality following widowhood in Norway.

This paper examines the short-term risk of cause-specific death following widowhood. We followed all individuals registered as married in Norway in 1975 for marital status and mortality until 2006. Widowed individuals were followed for mortality for 7years following widowhood. Causes of death were categorized into five cause-groups. Life tables were used in survival analyses. Deaths among the widowed were most frequent in the week following widowhood. In this week and compared to married individuals, there were more deaths including those from malignant cancer in men (hazard ratio (HR) of 1.51; 95% CI: 1.12, 1.89), from external causes in men (HR=3.64; 95% CI: 2.01, 5.28), and from respiratory diseases (HR=2.18; 95% CI: 1.52, 2.84 in men and HR=3.18; 95% CI: 2.26, 4.09 in women). A majority of respiratory deaths were from pneumonia. Thereafter excess mortality among the widowed dropped gradually. Although these numbers stabilized, they were still elevated in year 7. Excess mortality was particularly high in the youngest age group considered (55-64years) and decreased with age, though more so in men than in women. Only a few more widowed individuals than expected died of a condition in the same cause-group as their spouses. A novel finding was that excess deaths in the week following widowhood also were from cancer and respiratory diseases. Men in the youngest age group seemed most vulnerable. Prevention should be considered directly after the death of a spouse, and measures should be aimed at virtually all causes of death. Copyright © 2016 Elsevier Inc. All rights reserved.

Although physical activity has substantial health benefits and reduces mortality, few studies have examined its impact on survival beyond age 75. Using the population-based Leisure World Cohort Study, we explored the association of activity on all-cause mortality in older adults (median age at baseline = 74 years). We followed 8,371 women and 4,828 men for 28 years or until death (median = 13 years) and calculated relative risks for various measures of activity at baseline using Cox regression analysis for four age groups (<70, 70-74, 75-79, and 80+ years) in men and women separately. Time spent in active activities, even ½ hour/day, resulted in significantly lower (15-35%) mortality risks compared with no time in active activities. This reduction was evident in all sex-age groups except the youngest men. Participants who reported spending 6 or more hours/day in other less physically demanding activities also had significantly reduced risks of death of 15-30%. The beneficial effect of activities was observed in both those who did and those who did not cut down their activities due to illness or injury. Neither adjustment for potential confounders, exclusion of the first 5 years of follow-up, nor exclusion of individuals with histories of chronic disease substantially changed the findings. Participation in leisure-time activities is an important health promoter in aging populations. The association of less physically demanding activities as well as traditional physical activities involving moderate exertion with reduced mortality suggests that the protective effect of engagement in activities is a robust one.

The epidemiology of bacterial meningitis varies in different areas, age groups, and times. To know the trend of neonatal and childhood bacterial meningitis in northern Taiwan, we performed this 29-year-long assessment. Eligible patients were aged 18 years or younger, hospitalized in Mackay Memorial Hospital between 1984 and 2012, and proven by positive cerebrospinal fluid bacterial cultures. Analysis included the patient numbers and pathogens in different age groups, periods, complications, and outcomes. Males were predominant in all the age groups through the years. Almost half of the patients were in the neonatal period. Patient numbers went up in the early study period and declined after 1993-1997. Group B Streptococcus and Escherichia coli were the most common pathogens in neonates, whereas in childhood were Streptococcus pneumoniae and Haemophilus influenzae type b (Hib). Patient numbers of Group B Streptococcus, S. pneumoniae, and Hib meningitis declined in the late study period, but E. coli meningitis increased. The mortality rate decreased but sequela rate increased. Among the four most common pathogens, S. pneumoniae had the worst outcome and had highest mortality rate. All Hib meningitis patients survived, but their sequela rate was the highest. This study provides an epidemiological data on trends of neonatal and childhood bacterial meningitis in northern Taiwan during the past 29 years, including male and neonatal predominance, decrease of total patient number in recent years, change of major pathogens, and declined mortality but raised morbidity.

The objectives were to clarify the trend in the cause-specific mortality rate and changes in health and long-term-care use after the Great East Japan Earthquake in 2011. We obtained the following data from national sources: the number of deaths by cause, age and month; the amount of healthcare insurance expenditures by type of services, age and month; the amount of long-term-care insurance expenditures by type of services, age, care need and month. We estimated increase in standardised mortality rate postearthquake compared with pre-earthquake, and change in the standardised amount of health and long-term-care insurance expenditures post-earthquake compared with pre-earthquake in three severely affected prefectures, Iwate, Miyagi and Fukushima, by the adjustment for trends in the other prefectures. The risk of indirect mortality increased in the month of the earthquake (relative risk (RR) with 95% CI 1.20 (1.13 to 1.28) for those 60-69 years of age, 1.25 (1.17 to 1.32) for 70-79 years, and 1.33 (1.27 to 1.38) for 80 years and older). The amount of health and long-term-care insurance expenditures decreased among elderly persons in the month of the earthquake, and recovered to 95% of usual level within 1-5 months. Among cities and towns hit by tsunami, higher percentage of households flooded was associated with higher risk of indirect mortality (p<0.001), lower expenditures for outpatient medical care (p<0.001), and lower expenditures for home-care services (p<0.001). This study showed transient increase in indirect mortality and recovery of health and long-term-care system after the earthquake. Published by the BMJ Publishing Group Limited.

Though the cardiovascular diseases are the leading cause of mortality in India, little is known about the human and economic loss attributed to the disease. The aim of this paper is to account the age and sex pattern of mortality, hospitalisation and the cost of hospitalisation for cardiovascular diseases in India. Data for the present study has been drawn from multiple sources; 52(nd) and 60(th) rounds of the National Sample Survey, Special Survey of Death, 2001-03 and the Sample Registration System 2004-2010. Under the changing demographics and constant assumptions of mortality, hospitalisation and cost of hospitalisation, we have estimated the deaths, hospitalisation and cost of hospitalisation for cardiovascular diseases in India during 2004 to 2021. Descriptive analyses and multivariate techniques were used to understand the socio-economic differentials in cost of hospitalisation for cardiovascular diseases in India. In India, the cardiovascular diseases accounted for an estimated 1.4 million deaths in 2004 and it is likely to be 2.1 million in 2021. An estimated 6.7 million people were hospitalised for cardiovascular diseases in 2004, and projected to be 10.9 million by 2021. Unlike mortality, majority of the hospitalisation due to cardiovascular diseases will be in the prime working age group (25-59). The estimated cost of hospitalisation for cardiovascular diseases was 94/- billion rupees in 2004 and expected to be 152/- billion rupees by 2021, at 2004 prices. The cost of hospitalisation for cardiovascular diseases was significantly high in private health centres, high fertility states and among high socio-economic groups. The cardiovascular mortality and hospitalisation will be largely concentrated in the prime working age group and the cost of hospitalisation is expected to increase substantially in coming years. This calls for mobilising resources, increasing access to health insurance and devising strategies for the prevention, control and treatment of cardiovascular diseases in India.

Intra-dialytic hypertension is associated with high mortality in hemodialysis patients

2017-01-01

Background Intra-dialytic hypertension (IDH) is emerging as an important issue in hemodialysis patients. Its risk factors and clinical outcomes are unclear. Methods A total of 73 prevalent hemodialysis patients were enrolled. They included 14 (19.2%) patients with baseline IDH and 59 patients without IDH. Their clinical parameters, laboratory parameters, and mortality were investigated over 78 months. Results The risks factor of IDH included low serum potassium levels, low ultrafiltration, and low arm muscle area. Lower median survival was evident in the IDH group compared to the non-IDH group, but was not significantly different. After adjusting for relevant confounders for age, the IDH group displayed 2.846 times higher mortality rate than the non-IDH Group (adjusted hazard ratio: 2.846; 95% confidence interval: 1.081–7.490; P = 0.034). Conclusion IDH is associated with high mortality in hemodialysis patients. Clinicians should be aware of the risk factors. Future research studies are needed to explore the mechanisms involved in the association between IDH and mortality. PMID:28742805

Mass screening with abdominal ultrasonography (AUS) has been suggested as a tool to control adult hepatocellular carcinoma (HCC) in individuals, but its efficacy in reducing HCC mortality has never been demonstrated. This study aimed to assess the effectiveness of reducing HCC mortality by mass AUS screening for HCC based on a program designed and implemented in the Changhua Community-based Integrated Screening (CHCIS) program with an efficient invitation scheme guided by the risk score. We invited 11,114 (27.0%) of 41,219 eligible Taiwanese subjects between 45 and 69 years of age who resided in an HCC high-incidence area to attend a risk score-guided mass AUS screening between 2008 and 2010. The efficacy of reducing HCC mortality was estimated. Of the 8,962 AUS screening attendees (with an 80.6% attendance rate), a total of 16 confirmed HCC cases were identified through community-based ultrasonography screening. Among the 16 screen-detected HCC cases, only two died from HCC, indicating a favorable survival. The cumulative mortality due to HCC (per 100,000) was considerably lower in the invited AUS group (17.26) compared with the uninvited AUS group (42.87) and the historical control group (47.51), yielding age- and gender-adjusted relative mortality rates of 0.69 (95% confidence interval [CI]: 0.56-0.84) and 0.63 (95% CI: 0.52-0.77), respectively. Conclusion: The residents invited to community-based AUS screening for HCC, compared with those who were not invited, showed a reduction in HCC mortality by ∼31% among subjects aged 45-69 years who had not been included in the nationwide vaccination program against hepatitis B virus infection.

2015-10-01

COPD imposes a large public health burden internationally and in the United States. The objective of this study was to examine trends in mortality from COPD among US adults from 1968 to 2011. Data from the National Vital Statistics System from 1968 to 2011 for adults aged ≥ 25 years were accessed, and trends in mortality rates were examined with Joinpoint analysis. Among all adults, age-adjusted mortality rate rose from 29.4 per 100,000 population in 1968 to 67.0 per 100,000 population in 1999 and then declined to 63.7 per 100,000 population in 2011 (annual percentage change [APC] 2000-2011, -0.2%; 95% CI, -0.6 to 0.2). The age-adjusted mortality rate among men peaked in 1999 and then declined (APC 1999-2011, -1.1%; 95% CI, -1.4 to -0.7), whereas the age-adjusted mortality rate among women increased from 2000 to 2011, peaking in 2008 (APC 2000-2011, 0.4%; 95% CI, 0.0-0.9). Despite a narrowing of the sex gap, mortality rates in men continued to exceed those in women. Evidence of a decline in the APC was noted for black men (1999-2011, -1.5%; 95% CI, -2.1 to -1.0) and white men (1999-2011, -0.9%; 95% CI, -1.3 to -0.6), adults aged 55 to 64 years (1989-2011, -1.0%; 95% CI, -1.2 to -0.8), and adults aged 65 to 74 years (1999-2011, -1.2%; 95% CI, -1.6 to -0.9). In the United States, the mortality rate from COPD has declined since 1999 in men and some age groups but appears to be still rising in women, albeit at a reduced pace.

We assessed the prognostic value and limitations of Glasgow Coma Scale (GCS) and head Abbreviated Injury Score (AIS) and correlated head AIS with GCS. We studied 7,764 patients with head injuries. Bivariate analysis was performed to examine the relationship of GCS, head AIS, age, gender, and mechanism of injury with mortality. Stepwise logistic regression analysis was used to identify the independent risk factors associated with mortality. The overall mortality in the group of head injury patients with no other major extracranial injuries and no hypotension on admission was 9.3%. Logistic regression analysis identified head AIS, GCS, age, and mechanism of injury as significant independent risk factors of death. The prognostic value of GCS and head AIS was significantly affected by the mechanism of injury and the age of the patient. Patients with similar GCS or head AIS but different mechanisms of injury or ages had significantly different outcomes. The adjusted odds ratio of death in penetrating trauma was 5.2 (3.9, 7.0), p < 0.0001, and in the age group > or = 55 years the adjusted odds ratio was 3.4 (2.6, 4.6), p < 0.0001. There was no correlation between head AIS and GCS (correlation coefficient -0.31). Mechanism of injury and age have a major effect in the predictive value of GCS and head AIS. There is no good correlation between GCS and head AIS.

Background There is paucity of studies on socioeconomic inequalities in cancer mortality in developing countries. We examined trends in inequalities in cancer mortality by educational attainment in Colombia during a period of epidemiological transition and a rapid expansion of health insurance coverage. Methods Population mortality data (1998–2007) were linked to census data to obtain age-standardised cancer mortality rates by educational attainment at ages 25–64 years for stomach, cervical, prostate, lung, colorectal, breast and other cancers. We used Poisson regression to model mortality by educational attainment and estimated the contribution of specific cancers to the Slope Index of Inequality in cancer mortality. Results We observed large educational inequalities in cancer mortality, particularly for cancer of the cervix (RR primary versus tertiary groups=5.75, contributing 51% of cancer inequalities), stomach (RR=2.56 for males, contributing 49% of total cancer inequalities, and RR=1.98 for females, contributing 14% to total cancer inequalities), and lung (RR=1.64 for males contributing 17% of total cancer inequalities, and 1.32 for females contributing 5% to total cancer inequalities). Total cancer mortality rates declined faster among those with higher education, with the exception of mortality from cervical cancer, which declined more rapidly in the lower educational groups. Conclusion There are large socioeconomic inequalities in preventable cancer mortality in Colombia, which underscore the need for intensifying prevention efforts. Reducing cervical cancer through reducing HPV infection, early detection and improved access to treatment of preneoplasic lesions. Reinforcing anti-tobacco measures may be particularly important to curb inequalities in cancer mortality. PMID:25492898

Introduction In this retrospective study, we aimed to determine the risk factors for coronary artery bypass surgery in patients under 45 years of age, and evaluate the early postoperative results and the effect of gender. Methods A total of 324 patients under 45 years of age who undergone on-pump coronary artery bypass surgery between April 12, 2004 and January 10, 2012 were included to the study. Patients divided into groups as follows: Group 1 consisted of 269 males (mean age 41.3), Group 2 consisted of 55 females (mean age 41.6). Preoperative risk factors, intraoperative and postoperative data and early mortality rates of the groups were compared. Results Smoking rate was significantly higher in Group 1. Diabetes mellitus incidence and body mass index were significantly higher in Group 2 (P values P=0.01; P=0.0001; P=0.04 respectively). The aortic cross-clamping and cardiopulmonary bypass time and number of grafts per patient were significantly higher in Group 1 (P values P=0.04; P=0.04; P=0.002 respectively). There were no deaths in either group. Conclusion We found that gender has no effect on early mortality rates of the coronary bypass surgery patients under 45 years. PMID:25714211

This paper considers the suicide mortality trends from 1990-2009 in young people aged 15 to 19 years in Lithuania. Suicide and injury mortality data, plus mortality data from all causes, were used to compare the trend lines. Suicide mortality rate in young people aged 15-19 years and in all population showed a rising trend from 1990, and then a decreasing trend from 2002 year. This trend was significant exclusively in boys. When comparing suicide deaths as a percentage of injury deaths and of all deaths in the age group 15-19 years, rising trends for boys were evident, whilst in girls, there was no evidence of change. In Lithuania, from early 1990s, the frequency of suicide increased amongst adults and young people aged 15-19 years. After 2002, a decrease in deaths by suicide was observed both for the whole population and for young people aged 15-19 years. The rise and fall was obvious for boys. The reasons for different trends may have been influenced by the political and socioeconomic instability in the 1990-2002 period, and the socioeconomic stability, together with active preventive measures, from 2002. Although the consumption of modern Selective serotonin reuptake inhibitors (SSRIs) increased during the same time, suicide mortality was again high during the economic crisis in 2008-2009. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

Background Mortality/incidence predictions are used for allocating public health resources and should accurately reflect age-related changes through time. We present a new forecasting model for estimating future trends in age-related breast cancer mortality for the United States and England–Wales. Methods We used functional data analysis techniques both to model breast cancer mortality-age relationships in the United States from 1950 through 2001 and England–Wales from 1950 through 2003 and to estimate 20-year predictions using a new forecasting method. Results In the United States, trends for women aged 45 to 54 years have continued to decline since 1980. In contrast, trends in women aged 60 to 84 years increased in the 1980s and declined in the 1990s. For England–Wales, trends for women aged 45 to 74 years slightly increased before 1980, but declined thereafter. The greatest age-related changes for both regions were during the 1990s. For both the United States and England–Wales, trends are expected to decline and then stabilize, with the greatest decline in women aged 60 to 70 years. Forecasts suggest relatively stable trends for women older than 75 years. Conclusions Prediction of age-related changes in mortality/incidence can be used for planning and targeting programs for specific age groups. Currently, these models are being extended to incorporate other variables that may influence age-related changes in mortality/incidence trends. In their current form, these models will be most useful for modeling and projecting future trends of diseases for which there has been very little advancement in treatment and minimal cohort effects (eg. lethal cancers).

Although colorectal cancer (CRC) mortality rates are declining, racial-ethnic disparities in CRC mortality nationally are widening. Herein, the authors attempted to identify county-level variations in this pattern, and to characterize counties with improving disparity trends. The authors examined 20-year trends in US county-level black-white disparities in CRC age-adjusted mortality rates during the study period between 1989 and 2010. Using a mixed linear model, counties were grouped into mutually exclusive patterns of black-white racial disparity trends in age-adjusted CRC mortality across 20 three-year rolling average data points. County-level characteristics from census data and from the Area Health Resources File were normalized and entered into a principal component analysis. Multinomial logistic regression models were used to test the relation between these factors (clusters of related contextual variables) and the disparity trend pattern group for each county. Counties were grouped into 4 disparity trend pattern groups: 1) persistent disparity (parallel black and white trend lines); 2) diverging (widening disparity); 3) sustained equality; and 4) converging (moving from disparate outcomes toward equality). The initial principal component analysis clustered the 82 independent variables into a smaller number of components, 6 of which explained 47% of the county-level variation in disparity trend patterns. County-level variation in social determinants, health care workforce, and health systems all were found to contribute to variations in cancer mortality disparity trend patterns from 1990 through 2010. Counties sustaining equality over time or moving from disparities to equality in cancer mortality suggest that disparities are not inevitable, and provide hope that more communities can achieve optimal and equitable cancer outcomes for all.

This study investigates the impact of reproductive factors on the association between education and breast cancer mortality in Belgium. The role of reproductive factors has been investigated in several studies, with mixed results. Reproductive factors are either completely or partially responsible for the association between education and breast cancer mortality. The data consist of the 1991 census linked to registration data on cause-specific mortality during the period 1991-1995, including all breast cancer deaths in Belgium during the observation period. The study population includes all women aged 35-79 at time of the census. Age-standardized mortality rates and mortality rate ratios (Poisson regression) are computed for educational groups with and without control for reproductive factors. The population is stratified according to age (women aged 35-49 and 50-79) and according to nulliparity. The relationship between education and breast cancer is significant among postmenopausal women. Breast cancer mortality is higher among the higher educated women. These results are consistent with international findings, the gradient not being negative as in most other causes of death, but positive. Statistical control for parity and age at first birth reduces the association largely. In addition, among nonparous women, differences in breast cancer mortality by education are not consistent and generally not significant. Reproductive factors are largely responsible for the positive association between education and breast cancer mortality among postmenopausal women in Belgium. Among premenopausal women, the relation is not significant, a pattern consistent with international studies. Copyright © 2012 UICC.

This paper aimed to compare the profile of mortality from external causes among Seventh-day Adventists and the general population of Espírito Santo from 2003 to 2009. A search of Adventists was performed in the nominal database of the Mortality Information System containing data on Adventists provided by the administrative offices of the institution. Deaths from external causes occurred during the study period were then divided into two groups: Adventists and the general population. Adventists had lower proportional mortality from external causes (10%) than the general population (19%), and males were the main reason for this difference. In both groups, deaths prevailed in the 20-29 years age group. Deaths from accidental causes were most significant among Adventists (68.08%), while deaths from intentional causes related to assault and self-inflicted injuries were more significant in the general population (53.67% of all deaths). The standardized mortality ratio for external causes was 41.3, thus, being Adventist reduced mortality by 58.7%. It is believed that the benefit of Adventists observed for mortality from external causes is related to this group's abstinence from alcohol consumption.

Background The 1918 influenza pandemic caused disproportionately high mortality among certain age groups. The mechanisms underlying these differences are not fully understood. Objectives To explore the dynamics of the 1918 pandemic and to identify potential age-specific transmission patterns. Methods We examined 1915–1923 daily mortality data in New York City (NYC) and estimated the outbreak duration and initial effective reproductive number (Re) for each 1-year age cohort. Results Four pandemic waves occurred from February 1918 to April 1920. The fractional mortality increase (i.e. ratio of excess mortality to baseline mortality) was highest among teenagers during the first wave. This peak shifted to 25- to 29-year-olds in subsequent waves. The distribution of age-specific mortality during the last three waves was strongly correlated (r = 0·94 and 0·86). With each wave, the pandemic appeared to spread with a comparable early growth rate but then attenuate with varying rates. For the entire population, Re estimates made assuming 2-day serial interval were 1·74 (1·27), 1·74 (1·43), 1·66 (1·25), and 1·86 (1·37), respectively, during the first week (first 3 weeks) of each wave. Using age-specific mortality, the average Re estimates over the first week of each wave were 1·62 (95% CI: 1·55–1·68), 1·68 (1·65–1·72), 1·67 (1·61–1·73), and 1·69 (1·63–1·74), respectively; Re was not significantly different either among age cohorts or between waves. Conclusions The pandemic generally caused higher mortality among young adults and might have spread mainly among school-aged children during the first wave. We propose mechanisms to explain the timing and transmission dynamics of the four NYC pandemic waves. PMID:24299150

Previous studies suggest that mortality from congenital heart diseases (CHDs) is declining in the United States. But we do not know what the CHD mortality trend is in China, especially the rural versus urban patterns. Our study aimed to determine recent changes in death caused by CHD in China and describe CHD mortality in rural and urban Chinese populations. The data source was the China Ministry of Health 2003 to 2010 annual reports. Mortality was defined as death caused by CHD. Mortality rates for each year were calculated per 10,000,000 person-years. Poisson regression and descriptive analyses were conducted for overall trend and subgroup analysis was conducted by sex, age, and urban versus rural residency to understand potential disparities in mortality. From 2003 to 2010, the overall mortality rate increased from 141 per 10,000,000 person-years in 2003 to 229 per 10,000,000 person-years in 2010, a 62.4% relative increase. This represents a region-sex adjusted annual increase of 9% (incidence rate ratio, 1.09; 95% confidence interval, 1.09-1.10). The increase in CHD mortality was not uniformly observed across age groups, urban versus rural residence, and sex. The relative increases were 65.3%, 212.2%, and 131.7% for ages 1 to 10 years, 21 to 64 years, and 65 years or older groups, respectively. Urban areas had a relative increase of 154.5% versus 5.3% for rural areas. Females who lived in an urban environment had a relative increase of 313.5%. Our observation showed an obvious increasing trend of CHD mortality in China. What is more, the increase in CHD mortality was not uniformly observed across subgroups. Such information is needed for strategy-making procedures. Copyright © 2014 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

Small-area mortality atlases have been demonstrated to be a useful tool for both showing general geographical patterns in mortality data and identifying specific high-risk locations. In Spain no study has so far systematically examined geographic patterns of small-area mortality for the main causes of death. This paper presents the main features, contents and potential uses of the Spanish Atlas of Mortality in small areas (1987-1995). Population data for 2,218 small areas were drawn from the 1991 Census. Aggregated mortality data for 14 specific causes of death for the period 1987-1995 were obtained for each small area. Empirical Bayes-model-based estimates of age-adjusted relative risk were displayed in small-area maps for each cause/gender/age group (0-64 or 65 and over) combination using the same range of values (i.e. septiles) and colour schemes. The 'Spanish Atlas of Mortality' includes multiple choropleth (area-shaded) small-area maps and graphs to answer different questions about the data. The atlas is divided into three main sections. Section 1 includes the methods and comments on the main maps. Section 2 presents a two-page layout for each leading cause of death by gender including 1) a large map with relative risk estimates, 2) a map that indicates high- and low-risk small areas, 3) a graph with median and interquartile range of relative risk estimates for 17 large regions of Spain, and 4) relative-risk maps for two age groups. Section 3 provides specific information on the geographical units of analysis, statistical methods and other supplemental maps. The 'Spanish Atlas of Mortality' is a useful tool for examining geographical patterns of mortality risk and identifying specific high-risk areas. Mortality patterns displayed in the atlas may have important implications for research and social/health policy planning purposes.

This study used life table methods to evaluate the potential effects of reduction in major disease mortality on life expectancy in New South Wales (NSW), and the differences in cause-specific mortality between country of birth groups. The total and partial elimination of major causes of death were examined to identify the high-risk groups for community-level health planning. Life tables were used to combine the mortality rates of the NSW population at different ages into a single statistical model. Using abridged, multiple decrement and cause-elimination life tables with the mortality data for NSW in 2000-2002, broader disease groups were examined. Multiple decrement tables were generated by country of birth. The effect of the partial elimination of ischaemic heart disease (IHD) was also studied. This study found that Pacific-born men and women who reach their 30th birthday and eventually die from IHD are expected to live, on average, 10.8 and 5.8 years less, respectively, than average men and women in NSW. If IHD is eliminated as a cause of death, 7.5 years for males and 6.7 years for females would be added to life expectancy at birth. Life expectancy at birth is likely to be further increased by reducing deaths caused by diseases of the cardiovascular system, particularly among people aged over 65 years, by reducing malignant neoplasm deaths among those aged below 65 years, and by reducing deaths due to accidents, injury and poisoning, mainly among men aged 15-29 years. Further gains in life expectancy could be achieved with community-level educational programmes on lifestyle management and disease prevention.

Background Insufficient data exist on population-based trends in morbidity and mortality to determine the success of prevention strategies and improvements in health care delivery in stroke. The aim of this study was to determine trends in incidence and outcome (1-year mortality, 28-day case-fatality) in relation to management and risk factors for stroke in the multi-ethnic population of Auckland, New Zealand (NZ) over 30-years. Methods Four stroke incidence population-based register studies were undertaken in adult residents (aged ≥15 years) of Auckland NZ in 1981–1982, 1991–1992, 2002–2003 and 2011–2012. All used standard World Health Organization (WHO) diagnostic criteria and multiple overlapping sources of case-ascertainment for hospitalised and non-hospitalised, fatal and non-fatal, new stroke events. Ethnicity was consistently self-identified into four major groups. Crude and age-adjusted (WHO world population standard) annual incidence and mortality with corresponding 95% confidence intervals (CI) were calculated per 100,000 people, assuming a Poisson distribution. Results 5400 new stroke patients were registered in four 12 month recruitment phases over the 30-year study period; 79% were NZ/European, 6% Māori, 8% Pacific people, and 7% were of Asian or other origin. Overall stroke incidence and 1-year mortality decreased by 23% (95% CI 5%-31%) and 62% (95% CI 36%-86%), respectively, from 1981 to 2012. Whilst stroke incidence and mortality declined across all groups in NZ from 1991, Māori and Pacific groups had the slowest rate of decline and continue to experience stroke at a significantly younger age (mean ages 60 and 62 years, respectively) compared with NZ/Europeans (mean age 75 years). There was also a decline in 28-day stroke case fatality (overall by 14%, 95% CI 11%-17%) across all ethnic groups from 1981 to 2012. However, there were significant increases in the frequencies of pre-morbid hypertension, myocardial infarction, and diabetes mellitus, but a reduction in frequency of current smoking among stroke patients. Conclusions In this unique temporal series of studies spanning 30 years, stroke incidence, early case-fatality and 1-year mortality have declined, but ethnic disparities in risk and outcome for stroke persisted suggesting that primary stroke prevention remains crucial to reducing the burden of this disease.

Age is associated with reduced exercise capacity and greater prevalence of coronary artery disease. Whether the prognostic information obtained from dobutamine stress echocardiography (DSE), a stress test commonly used for patients unable to perform an exercise test, provides differential information based on age is not well known. We studied 6,655 consecutive patients referred for DSE. Patients were divided into 3 age groups: (1) <60 years (n = 1,389), (2) 60 to 74 years (n = 2,978), and (3) ≥75 years (n = 2,288). Mean follow-up was 5.5 ± 2.8 years. End points included all-cause mortality and cardiac events, including myocardial infarction and late (>3 months) coronary revascularization. Peak stress wall motion score index was an independent predictor of cardiac events in all age groups (<60 years: hazard ratio [HR] 1.14, P = .02; 60-74 years: HR 1.70, P < .0001; ≥75 years: HR 1.10, P = .006). In patients ≥75 years, peak wall motion score index (HR 1.10, P < .0001) and abnormal left ventricular end-systolic volume response (HR 1.25, P = .03) were independent predictors of death. In patients aged 60 to 74 years, abnormal left ventricular end-systolic volume response (HR 1.43, P = .0003) was independently related to death, whereas in patients <60 years, the echocardiographic data assessed during stress were not a predictor. Dobutamine stress echocardiography provided independent information predictive of cardiac events among all age groups and death in patients ≥60 years. However, among patients <60 years, stress-induced echocardiographic abnormalities were not independently associated with mortality. Comorbidities, which have precluded exercise testing, may be most relevant in predicting mortality in patients <60 years undergoing DSE. Copyright © 2011 Mosby, Inc. All rights reserved.

Age of renal transplants has been related to death, alloimmune response and graft outcome. We reviewed the influence of patient age on transplant outcome in three cohorts of patients transplanted in Spain during the 1990 s. Patient age was categorized into four groups (I, 18-40; II, 41-50; III, 51-60; and IV, > 60 years). Risks factors for acute rejection were evaluated by logistic regression adjusting for transplant centre and transplantation year, while a Cox proportional hazard model was employed for analysing patient and graft survival. Older patients had a higher death rate (I, 3.5%; II, 7.7%; III, 13.2%; and IV, 16.9%; P<0.001), but a lower standardized mortality index (I, 7.6; II, 7.0; III, 5.8; and IV, 4.1; P = 0.0019). Older patients had the lowest risk of acute rejection [odds ratio (OR) 0.79 and 95% confidence interval (CI) 0.66-0.97 for group II; OR 0.75 and 95% CI 0.62-0.91 for group III; OR 0.43 and 95% CI 0.33-0.56 for group IV). Death-censored graft survival was poorer in patients older than 60 years (relative risk 1.40; 95% CI 1.09-1.80), but this result was not explained by any combination of patient age with donor age, delayed graft function or immunosuppression. Patient age is a main determinant of transplant outcome. Although death rate is higher for older patients, standardized mortality was not. Thus, the efforts to reduce mortality should be also implemented in younger patients. Old patients have a low risk of acute rejection but a poorer death-censored graft survival. This last result was not explained by any controlled variable in our study.

The oldest old represent a unique group of older adults. This group is rapidly growing worldwide and yet there are gaps in the knowledge related to their health condition. Ethnic differences in disease prevalence and mortality must be understood to better care for the oldest old. To compare prevalence of common health conditions and predictors of mortality in oldest old Mexican Americans and non-Hispanic whites. This study included 568 community-dwelling Mexican Americans (MA) aged 85 years and older from the Hispanic Established Population for the Epidemiological Study of the Elderly 2004-2005 and 933 non-Hispanic whites (NHW) of the same age from the Health and Retirement Study 2004. Measures included sociodemographic variables, self-reported medical conditions, activities of daily living (ADLs), and instrumental activities of daily living. Logistic regression analysis was used to examine 2-year mortality in both populations. Heart attack was significantly more prevalent in oldest old NHW compared with MA, regardless of gender. Conversely, diabetes was significantly more prevalent among MA men and women compared with their NHW counterparts. Compared with NHW men, MA men had significantly higher prevalence of cognitive impairment and hypertension. Additionally, prevalence of hip fracture was significantly higher for MA women compared with NHW women. Significant differences in ADL disability were observed only between both groups of women, whereas significant differences in instrumental activities of daily living disability were observed only between men. MA men and women had higher prevalence of obesity compared with NHW. Predictors of 2-year mortality for both ethnic groups included older age, male gender, and ADL disability. Cognitive impairment was a mortality predictor only for NHW. Similarly, lung disease was a predictor only for MA. Health-related conditions that affect the oldest old vary by gender and ethnicity and entail careful evaluation and monitoring in the clinical setting. Better care requires inclusion of such differences as part of the comprehensive evaluation of the oldest old adults. Published by Elsevier Inc.

Adults who experience prolonged homelessness have mortality rates 3 to 4 times that of the general population. Housing First (HF) is an evidence-based practice that effectively ends chronic homelessness, yet there has been virtually no research on premature mortality among HF enrollees. In the United States, this gap in the literature exists despite research that has suggested chronically homeless adults constitute an aging cohort, with nearly half aged 50 years old or older. This observational study examined mortality among formerly homeless adults in an HF program. We examined death rates and causes of death among HF participants and assessed the timing and predictors of death among HF participants following entry into housing. We also compared mortality rates between HF participants and (a) members of the general population and (b) individuals experiencing homelessness. We supplemented these analyses with a comparison of the causes of death and characteristics of decedents in the HF program with a sample of adults identified as homeless in the same city at the time of death through a formal review process. The majority of decedents in both groups were between the ages of 45 and 64 at their time of death; the average age at death for HF participants was 57, compared to 53 for individuals in the homeless sample. Among those in the HF group, 72% died from natural causes, compared to 49% from the homeless group. This included 21% of HF participants and 7% from the homeless group who died from cancer. Among homeless adults, 40% died from an accident, which was significantly more than the 14% of HF participants who died from an accident. HIV or other infectious diseases contributed to 13% of homeless deaths compared to only 2% of HF participants. Hypothermia contributed to 6% of homeless deaths, which was not a cause of death for HF participants. Results suggest HF participants face excess mortality in comparison to members of the general population and that mortality rates among HF participants are higher than among those reported among members of the general homeless population in prior studies. However, findings also suggest that causes of death may differ between HF participants and their homeless counterparts. Specifically, chronic diseases appear to be more prominent causes of death among HF participants, indicating the potential need for integrating medical support and end-of-life care in HF.

There have been no previous estimates on differences in adult or overall mortality in indigenous peoples in Brazil, although such indicators are extremely important for reducing social iniquities in health in this population segment. Brazil has made significant strides in recent decades to fill the gaps in data on indigenous peoples in the national statistics. The aim of this paper is to present estimated mortality rates for indigenous and non-indigenous persons in different age groups, based on data from the 2010 Population Census. The estimates used the question on deaths from specific household surveys. The results indicate important differences in mortality rates between indigenous and non-indigenous persons in all the selected age groups and in both sexes. These differences are more pronounced in childhood, especially in girls. The indicators corroborate the fact that indigenous peoples in Brazil are in a situation of extreme vulnerability in terms of their health, based on these unprecedented estimates of the size of these differences.

Mortality rates generally decline during economic recessions in high-income countries, however gaps remain in our understanding of the underlying mechanisms. This study estimates the impacts of increases in unemployment rates on both all-cause and cause-specific mortality across U.S. metropolitan regions during the Great Recession. We estimate the effects of economic conditions during the recent and severe recessionary period on mortality, including differences by age and gender subgroups, using fixed effects regression models. We identify a plausibly causal effect by isolating the impacts of within-metropolitan area changes in unemployment rates and controlling for common temporal trends. We aggregated vital statistics, population, and unemployment data at the area-month-year-age-gender-race level, yielding 527,040 observations across 366 metropolitan areas, 2005-2010. We estimate that a one percentage point increase in the metropolitan area unemployment rate was associated with a decrease in all-cause mortality of 3.95 deaths per 100,000 person years (95%CI -6.80 to -1.10), or 0.5%. Estimated reductions in cardiovascular disease mortality contributed 60% of the overall effect and were more pronounced among women. Motor vehicle accident mortality declined with unemployment increases, especially for men and those under age 65, as did legal intervention and homicide mortality, particularly for men and adults ages 25-64. We find suggestive evidence that increases in metropolitan area unemployment increased accidental drug poisoning deaths for both men and women ages 25-64. Our finding that all-cause mortality decreased during the Great Recession is consistent with previous studies. Some categories of cause-specific mortality, notably cardiovascular disease, also follow this pattern, and are more pronounced for certain gender and age groups. Our study also suggests that the recent recession contributed to the growth in deaths from overdoses of prescription drugs in working-age adults in metropolitan areas. Additional research investigating the mechanisms underlying the health consequences of macroeconomic conditions is warranted. Copyright © 2017 Elsevier Ltd. All rights reserved.

To analyze the trend in mortality from cerebrovascular diseases in Costa Rica and its impact on overall mortality from 1920 to 2009. Crude rates by triennium and quinquennium were obtained. We also obtanied age standardized rates in the age group 35-74 years during the period 1970-2009. Finally we got the death percentage from stroke in relation to overall mortality. The trend for the period 1920-1969 was to the upside (r=0.82, r 2 =0.67, betha 0.30; P≤0.00) whereas for the period 1970 occurred otherwise (r=0.42, r 2 =0.18, betha -0064; P=0.01). Adjusted for the group 35-74 years between 1970-2009 rates decreased by 58.03% was statistically significant trend for both sexes; men r2=0.94, betha: -0.73; women: r2=0.97, betha: 0.95. The maximum percentage of mortality from stroke in relation to the overall mortality was 7.22 in the period 1985-1989 reached down to 5.92% in 2005-2009. In the Latin American context, stroke mortality rates in Costa Rica are low but still represent a serious public health problem by the high mortality, morbidity and disability that they cause, despite a downward trend.

Heterogeneity in the Strehler-Mildvan general theory of mortality and aging.

PubMed

2011-02-01

This study examines and further develops the classic Strehler-Mildvan (SM) general theory of mortality and aging. Three predictions from the SM theory are tested by examining the age dependence of mortality patterns for 42 countries (including developed and developing countries) over the period 1955-2003. By applying finite mixture regression models, principal component analysis, and random-effects panel regression models, we find that (1) the negative correlation between the initial adulthood mortality rate and the rate of increase in mortality with age derived in the SM theory exists but is not constant; (2) within the SM framework, the implied age of expected zero vitality (expected maximum survival age) also is variable over time; (3) longevity trajectories are not homogeneous among the countries; (4) Central American and Southeast Asian countries have higher expected age of zero vitality than other countries in spite of relatively disadvantageous national ecological systems; (5) within the group of Central American and Southeast Asian countries, a more disadvantageous national ecological system is associated with a higher expected age of zero vitality; and (6) larger agricultural and food productivities, higher labor participation rates, higher percentages of population living in urban areas, and larger GDP per capita and GDP per unit of energy use are important beneficial national ecological system factors that can promote survival. These findings indicate that the SM theory needs to be generalized to incorporate heterogeneity among human populations.

Colorectal cancer is a leading cause of death worldwide for men and women, and one of the most commonly diagnosed in Córdoba, Argentina. The aim of this work was to provide an up-to-date approach to descriptive epidemiology of colorectal cancer in Córdoba throughout the estimation of mortality trends in the period 1986-2006, using Joinpoint and age-period-cohort (APC) models. Age-standardized (world population) mortality rates (ASMR), overall and truncated (35-64 years), were calculated and Joinpoint regression performed to compute the estimated annual percentage changes (EAPC). Poisson sequential models were fitted to estimate the effect of age (11 age groups), period (1986-1990, 1991-1995, 1996-2000 or 2001-2006) and cohort (13 ten-years cohorts overlapping each other by five-years) on colorectal cancer mortality rates. ASMR showed an overall significant decrease (EAPC -0.9 95%CI: -1.7, -0.2) for women, being more noticeable from 1996 onwards (EAPC -2.1 95%CI: -4.0, -0.1). Age-effect showed an important rise in both sexes, but more evident in males. Birth cohort- and period effects reflected increasing and decreasing tendencies for men and women, respectively. Differences in mortality rates were found according to sex and could be related to age-period-cohort effects linked to the ageing process, health care and lifestyle. Further research is needed to elucidate the specific age-, period- and cohort-related factors.

Our aim was to assess the possible impact of a deterioration of renal function (DRF) not fulfilling the criteria for acute kidney injury after percutaneous coronary intervention (PCI) on outcome in patients with ST-elevation myocardial infarction (STEMI) on 30-day and long-term outcomes. Data is lacking on the influence of DRF after PCI on outcome in patients with STEMI. The present study is an analysis of 2572 STEMI patients who underwent PCI. The group with DRF (1022 patients) and the group without DRF (1550 patients) were compared. Thirty-day and long-term all-cause mortality were observed. Data was analyzed using descriptive statistics. Similar mortality was observed in both groups at day 30 (4.2% patients with DRF died vs 3.2% without DRF; ns) but more patients had died in the DRF group (18.9% patients with DRF vs 14.0% without DRF; P = 0.001) by the end of the observation period. After adjustments, DRF did not independently predict long-term mortality. Age more than 70 years, bleeding, hyperlipidemia, renal dysfunction on admission, anemia on admission, diabetes, PCI of LAD, the use of more than 200 mL contrast, but not DRF after PCI, were identified as independent prognostic factors for increased long-term mortality. Renal dysfunction, bleeding, contrast >200 mL, hyperlipidemia, age >70 years, anemia, and PCI LAD predicted DRF. DRF identified patients at increased risk of higher long-term mortality but was not independently associated with mortality. © 2017, Wiley Periodicals, Inc.

Suicide is an important public health problem, it represents one of the major causes of unnatural death, and there are many factors that affect the risk of suicidal behaviour. The present study analyzes the temporal and spatial variations of mortality by suicide in Spain and its relationship with gross domestic product (GDP) per capita. A retrospective study was performed, in which deaths by suicide, sex and age group in 50 Spanish provinces between 2000 and 2012 were analyzed. The annual trend of suicide mortality was assessed using Kendall's tau-b correlation coefficient. Seasonality and monthly and weekly behaviour were evaluated by performing the ANOVA test and the Bonferroni adjustment. Finally, the relationship between GDP per capita and suicide was studied. Between 2000 and 2012, 42,905adult people died by suicide in Spain. The annual average incidence rate was 95 suicides per million population. The regions located in the south and in the northwest of the country registered the highest per capita mortality rates. There is a decreasing trend in mortality by suicide over the period studied (CC=-.744; P=.0004) in adults over the age of 64, and a seasonal behaviour was identified with summer maximum and autumn minimum values (f=.504; P<.0001). The regions with the highest GDP per capita showed the lowest mortality by suicide (r=-.645; P<.0001) and the relationship is stronger among older age groups. Mortality by suicide does not follow a homogenous geographical distribution in Spain. Mortality in men was higher than in women. Over the period of study, there has been a decrease in mortality by suicide in Spain in adults over the age of 64. The seasonal cycle of suicides and the inverse relationship with GDP per capita found in this study, provide information which may be used as a tool for developing prevention and intervention strategies.

In 1968, a B-52 bomber carrying nuclear bombs crashed near the Thule US Air-Base in Greenland. By 1986, many cases of disease had been reported among Danish workers employed at the base. A database has been constructed from staff files of workers employed from 1963 to 1971. Of 4,322 workers, 98.7% were identified in 1987. The study group consisted of 1,202 workers employed during the clean up period (from the time of the crash until the last of the contaminated material had been removed). The reference group consisted of 3,120 workers employed outside the clean up period. No differences were found in total mortality, or mortality from cancer, heart disease or accidents between the groups after adjusting for age, marital status and length of employment. Mortality from suicide was lower in the study group. The hospitalization rates for the period 1977-1985 also showed no differences between the two groups. The conclusion of the register surveys is that no harmful effect on health due to the crash can be established by measuring mortality or hospital admissions.

Crooks, Colin; Card, Tim; West, Joe

2011-01-01

Background & Aims It is unclear whether mortality from upper gastrointestinal hemorrhage is changing: any differences observed might result from changes in age or comorbidity of patient populations. We estimated trends in 28-day mortality in England following hospital admission for gastrointestinal hemorrhage. Methods We used a case-control study design to analyze data from all adults administered to a National Health Service hospital, for upper gastrointestinal hemorrhage, from 1999 to 2007 (n = 516,153). Cases were deaths within 28 days of admission (n = 74,992), and controls were survivors to 28 days. The 28-day mortality was derived from the linked national death register. A logistic regression model was used to adjust trends in nonvariceal and variceal hemorrhage mortality for age, sex, and comorbidities and to investigate potential interactions. Results During the study period, the unadjusted, overall, 28-day mortality following nonvariceal hemorrhage was reduced from 14.7% to 13.1% (unadjusted odds ratio, 0.87; 95% confidence interval: 0.84–0.90). The mortality following variceal hemorrhage was reduced from 24.6% to 20.9% (unadjusted odds ratio, 0.8; 95% confidence interval: 0.69–0.95). Adjustments for age and comorbidity partly accounted for the observed trends in mortality. Different mortality trends were identified for different age groups following nonvariceal hemorrhage. Conclusions The 28-day mortality in England following both nonvariceal and variceal upper gastrointestinal hemorrhage decreased from 1999 to 2007, and the reduction had been partly obscured by changes in patient age and comorbidities. Our findings indicate that the overall management of bleeding has improved within the first 4 weeks of admission. PMID:21447331

Over the past decades, the decline in mortality from stroke has been more pronounced in high-income countries than in low- and middle-income countries. We evaluated changes in temporal stroke mortality trends in Mexico according to sex and type of stroke. We assessed stroke mortality from Mexico's National Health Information System for the period from 1980 to 2012. We analyzed age-adjusted mortality rates by sex, type of stroke, and age group. The annual percentage change and the average annual percentage change (AAPC) in the slopes of the age-adjusted mortality trends were determined using joinpoint regression models. The age-adjusted mortality rates due to stroke decreased between 1980 and 2012, from 44.55 to 33.47 per 100,000 inhabitants, and the AAPC (95% confidence interval [CI]) was -.9 (-1.0 to -.7). The AAPC for females was -1.1 (-1.5 to -.7) and that for males was -.7 (-.9 to -.6). People older than 65 years showed the highest mortality throughout the period. Between 1980 and 2012, the AAPC (95% CI) for ischemic stroke was -3.8 (-4.8 to -2.8) and was -.5 (-.8 to -.2) for hemorrhagic stroke. For the same period, the AAPC for intracerebral hemorrhage (ICH) was -.7 (-1.6 to .2) and that for subarachnoid hemorrhage (SAH) was 1.6 (.4-2.8). The age-adjusted mortality rates of all strokes combined, ischemic stroke, hemorrhagic stroke, and ICH, decreased between 1980 and 2012 in Mexico. However, the increase in SAH mortality makes it necessary to explore the risk factors and clinical management of this type of stroke. Copyright © 2017 National Stroke Association.

This report is a descriptive study on suicide deaths in Louisiana occurring in the years 1999 to 2010. Mortality data was collected from death certificates from this 12-year period to describe suicide mortality by year, race, sex, age group, and methods of suicide. Data were also compared to national data. Rates and methods used to commit suicide vary greatly according to sex, race, and age. The highest rates were observed in white males, followed by black males, white females, and black females. Older white males had the highest suicide rates. The influence of age was modulated by the sex and race categories. Firearm was the most common method used in all four categories. Other less common methods were hanging/strangulation/suffocation (HSS) and drugs/alcohol. Although no parish-level data were systematically analyzed, a comparison of suicide rates post-Katrina versus pre-Katrina was done for Orleans Parish, the rest of the Greater New Orleans area, and a comparison group. It appears that rates observed among whites, particularly males, were higher after Katrina. Data based on mortality do not give a comprehensive picture of the burden of suicide, and their interpretation should be done with caution.

The objective of this study was to critically examine potential artifacts and biases underlying the use of 'customised' standards of birthweight for gestational age (GA). Population-based cohort study. Sweden. A total of 782,303 singletons > or =28 weeks of gestation born in 1992-2001 to Nordic mothers with complete data on birthweight; GA; and maternal age, parity, height, and pre-pregnancy weight. We compared perinatal mortality in four groups of infants based on the following classification of small for gestational age (SGA): non-SGA based on either population-based or customised standards (the reference group), SGA based on the population-based standard only, SGA based on the customised standard only, and SGA according to both standards. We used graphical methods to compare GA-specific birthweight cutoffs for SGA using the two standards and also used logistic regression to control for differences in GA and maternal pre-pregnancy body mass index (BMI) in the four groups. Perinatal mortality, including stillbirth and neonatal death. Customisation led to a large artifactual increase in the proportion of SGA infants born preterm. Adjustment for differences in GA and maternal BMI markedly reduced the excess risk among infants classified as SGA by customised standards only. The large increase in perinatal mortality risk among infants classified as SGA based on customised standards is largely an artifact due to inclusion of more preterm births.

Pleural effusion is an abnormal collection of body fluids that may cause related morbidity or mortality in cirrhotic patients. There are insufficient data to determine the optimal method of drainage, for symptomatic relief in cirrhotic patients with pleural effusion. In this study, we compare the mortality outcomes of catheter drainage versus thoracentesis in cirrhotic patients. The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify cirrhotic patients with pleural effusion requiring drainage between January 1, 2007, and December 31, 2010. In all, 2556 cirrhotic patients with pleural effusion were selected for the study and divided into the two groups (n = 1278/group) after propensity score matching. The mean age was 61.0 ± 14.3 years, and 68.9% (1761/2556) were men. The overall 30-day mortality was 21.0% (538/2556) and was higher in patients treated with catheter drainage than those treated with thoracentesis (23.5 vs. 18.6%, respectively, P < 0.001 by log-rank test). After Cox proportional hazard regression analysis adjusted by patient sex, age, and comorbid disorders, the risk of 30-day mortality was significantly higher in cirrhotic patients who accepted catheter drainage compared to thoracentesis (hazard ratio 1.30, 95% confidence interval 1.10-1.54, P = 0.003). Old age, hepatic encephalopathy, bleeding esophageal varices, hepatocellular carcinoma, ascites, and pneumonia were associated with higher risks for 30-day mortality. In cirrhotic patients with pleural effusion requiring drainage, catheter drainage is associated with higher mortality compared to thoracentesis.

Tuberculosis mortality trends in cuba, 1998 to 2007.

Introduction Tuberculosis (TB) is a major cause of illness and death throughout the world. The World Health Organization's Global Plan to Stop TB 2006-2015 proposes that countries cut TB mortality by half compared to 1990 rates. In Cuba, TB mortality declined steadily throughout the 20th century, particularly after 1960. Objective Describe TB mortality distribution and trends in Cuba from January 1998 to December 2007 by infection site, sex, age and province, and determine progress towards the WHO's 2015 target for TB mortality reduction. Methods A time series ecological study was conducted. Death certificates stating TB as cause of death were obtained from the Ministry of Public Health's National Statistics Division, and population data by age group, sex, and province were obtained from the National Statistics Bureau. Crude and specific death rate trends and variation were analyzed. Results TB mortality declined from 0.4 per 100,000 population in 1998 to 0.2 (under half the 1990 rate) in 2007. Clinical forms of the disease, both pulmonary and extrapulmonary, also declined. The highest mortality rates were found in males and in the group aged ≥ 65 years. Rates were also highest in the capital, Havana, with extreme values of 0.73 and 0.39 per 100,000 population at the beginning and end of the period, respectively. Conclusions Deaths from TB declined steadily compared to total deaths and deaths caused by infectious diseases. The Global Plan to Stop TB target was met well ahead of 2015. If this trend continues, TB is likely to become an exceptional cause of death in Cuba.

Social isolation, health literacy, and mortality risk: Findings from the English Longitudinal Study of Ageing.

To investigate the relationships between social isolation, health literacy, and all-cause mortality, and the modifying effect of social isolation on the latter relationship. Data were from 7731 adults aged ≥50 years participating in Wave 2 (2004/2005) of the English Longitudinal Study of Ageing. Social isolation was defined according to marital/cohabiting status and contact with children, relatives, and friends, and participation in social organizations. Scores were split at the median to indicate social isolation (yes vs. no). Health literacy was assessed as comprehension of a medicine label and classified as "high" (≥75% correct) or "low" (<75% correct). The outcome was all-cause mortality up to February 2013. Cox proportional hazards models were adjusted for sociodemographic factors, health status, health behaviors, and cognitive function. Mortality rates were 30.3% versus 14.3% in the low versus high health literacy groups, and 23.5% versus 13.7% in the socially isolated versus nonisolated groups. Low health literacy (adj. HR = 1.22, 95% CI 1.02-1.45 vs. high) and social isolation (adj. HR = 1.28, 95% CI 1.10-1.50) were independently associated with increased mortality risk. The multiplicative interaction term for health literacy and social isolation was not statistically significant (p = .81). Low health literacy and high social isolation are risk factors for mortality. Social isolation does not modify the relationship between health literacy and mortality. Clinicians should be aware of the health risks faced by socially isolated adults and those with low health literacy. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Mortality Due to Cardiovascular Disease Among Apollo Lunar Astronauts.

2017-05-01

Recent research has postulated increased cardiovascular mortality for astronauts who participated in the Apollo lunar missions. The conclusions, however, are based on small numbers of astronauts, are derived from methods with known weaknesses, and are not consistent with prior research. Records for NASA astronauts and U.S. Air Force astronauts were analyzed to produce standardized mortality ratios. Lunar astronauts were compared to astronauts who have never flown in space (nonflight astronauts), those who have only flown missions in low Earth orbit (LEO astronauts), and the U.S. general population. Lunar astronauts were significantly older at cohort entry than other astronaut group and lunar astronauts alive as of the end of 2015 were significantly older than nonflight astronauts and LEO astronauts. No significant differences in cardiovascular disease (CVD) mortality rates between astronaut groups was observed, though lunar astronauts were noted to be at significantly lower risk of death by CVD than are members of the U.S. general population (SMR = 13, 95% CI = 3-39). The differences in age structure between lunar and nonlunar astronauts and the deaths of LEO astronauts from external causes at young ages lead to confounding in proportional mortality studies of astronauts. When age and follow-up time are properly taken into account using cohort-based methods, no significant difference in CVD mortality rates is observed. Care should be taken to select the correct study design, outcome definition, exposure classification, and analysis when answering questions involving rare occupational exposures.Reynolds RJ, Day SM.

Determining the baseline mortality rate in a vaccinated population is necessary to be able to identify any unusual increases in deaths following vaccine administration. Background rates are particularly useful during mass immunization campaigns and in the evaluation of new vaccines. Provide background mortality rates and describe causes of death following vaccination in the Vaccine Safety Datalink (VSD). Analyses were conducted in 2012. Mortality rates were calculated at 0-1 day, 0-7 days, 0-30 days, and 0-60 days following vaccination for deaths occurring between January 1, 2005, and December 31, 2008. Analyses were stratified by age and gender. Causes of death were examined, and findings were compared to National Center for Health Statistics (NCHS) data. Among 13,033,274 vaccinated people, 15,455 deaths occurred between 0 and 60 days following vaccination. The mortality rate within 60 days of a vaccination visit was 442.5 deaths per 100,000 person-years. Rates were highest in the group aged ≥85 years, and increased from the 0-1-day to the 0-60-day interval following vaccination. Eleven of the 15 leading causes of death in the VSD and NCHS overlap in both systems, and the top four causes of death were the same in both systems. VSD mortality rates demonstrate a healthy vaccinee effect, with rates lowest in the days immediately following vaccination, most apparent in the older age groups. The VSD mortality rate is lower than that in the general U.S. population, and the causes of death are similar. Published by Elsevier Inc. on behalf of American Journal of Preventive Medicine

Mortality data by occupation are not routinely available in Canada, so we analyzed census-linked data to examine cause-specific mortality rates across groups of occupations ranked by skill level. A 15% sample of 1991 Canadian Census respondents aged 25 years or older was previously linked to 16 years of mortality data (1991-2006). The current analysis is based on 2.3 million people aged 25 to 64 years at cohort inception, among whom there were 164 332 deaths during the follow-up period. Occupations coded according to the National Occupation Classification were grouped into five skill levels. Age-standardized mortality rates (ASMRs), rate ratios (RRs), rate differences (RDs) and excess mortality were calculated by occupational skill level for various causes of death. ASMRs were clearly graded by skill level: they were highest among those employed in unskilled jobs (and those without an occupation) and lowest for those in professional occupations. All-cause RRs for men were 1.16, 1.40, 1.63 and 1.83 with decreasing occupational skill level compared with professionals. For women the gradient was less steep: 1.23, 1.24, 1.32 and 1.53. This gradient was present for most causes of death. Rate ratios comparing lowest to highest skill levels were greater than 2 for HIV/AIDS, diabetes mellitus, suicide and cancer of the cervix as well as for causes of death associated with tobacco use and excessive alcohol consumption. Mortality gradients by occupational skill level were evident for most causes of death. These results provide detailed cause-specific baseline indicators not previously available for Canada.

Inequalities in mortality during and after restructuring of the New Zealand economy: repeated cohort studies

PubMed Central

2008-01-01

Objectives To determine whether disparities between income and mortality changed during a period of major structural and macroeconomic reform and to estimate the changing contribution of different diseases to these disparities. Design Repeated cohort studies. Data sources 1981, 1986, 1991, 1996, and 2001 censuses linked to mortality data. Population Total New Zealand population, ages 1-74 years. Methods Mortality rates standardised for age and ethnicity were calculated for each census cohort by level of household income. Standardised rate differences and rate ratios, and slope and relative indices of inequality (SII and RII), were calculated to measure disparities on both absolute and relative scales. Results All cause mortality rates declined over the 25 year study period in all groups stratified by sex, age, and income, except for 25-44 year olds of both sexes on low incomes among whom there was little change. In all age groups pooled, relative inequalities increased from 1981-4 to 1996-9 (RIIs increased from 1.85 (95% confidence interval 1.67 to 2.04) to 2.54 (2.29 to 2.82) for males and from 1.54 (1.35 to 1.76) to 2.12 (1.88 to 2.39) for females), then stabilised in 2001-4 (RIIs of 2.60 (2.34 to 2.89) and 2.18 (1.93 to 2.45), respectively). Absolute inequalities were stable over time, with a possible fall from 1996-9 to 2001-4. Cardiovascular disease was the major contributor to the observed disparities between income and mortality but decreased in importance from 45% in 1981-4 to 33% in 2001-4 for males and from 50% to 29% for females. The corresponding contribution of cancer increased from 16% to 22% for males and from 12% to 25% for females. Conclusions During and after restructuring of the economy disparities in mortality between income groups in New Zealand increased in relative terms (but not in absolute terms), but it is difficult to confidently draw a causal link with structural reforms. The contribution of different causes of death to this inequality changed over time, indicating a need to re-prioritise health policy accordingly. PMID:18218998

Close to one in ten individuals worldwide is born preterm, and it is important to understand patterns of long-term health and mortality in this group. This study assesses the relationship between gestational age at birth and early adult mortality both in a nationwide population and within sibships. The study adds to existing knowledge by addressing selected causes of death and by assessing the role of genetic and environmental factors shared by siblings. Study population was all Norwegian men and women born from 1967 to 1997 followed using nation-wide registry linkage for mortality through 2011 when they were between 15 and 45 years of age. Analyses were performed within maternal sibships to reduce variation in unobserved genetic and environmental factors shared by siblings. Specific outcomes were all-cause mortality and mortality from cardiovascular diseases, cancer and external causes including accidents, suicides and drug abuse/overdoses. Compared with a sibling born in week 37-41, preterm siblings born before 34 weeks gestation had 50% increased mortality from all causes (adjusted Hazard Ratio (aHR) 1.54, 95% confidence interval (CI) 1.17, 2.03). The corresponding estimate for the entire population was 1.27 (95% CI 1.09, 1.47). The majority of deaths (65%) were from external causes and the corresponding risk estimates for these deaths were 1.52 (95% CI 1.08, 2.14) in the sibships and 1.20 (95% CI 1.01, 1.43) in the population. Preterm birth before week 34 was associated with increased mortality between 15 and 45 years of age. The results suggest that increased premature adult mortality in this group is related to external causes of death and that the increased risks are unlikely to be explained by factors shared by siblings.

Many studies have documented higher mortality levels in the USA compared to other high-income nations. We add to this discussion by quantifying how many years behind comparison countries the USA has fallen and by identifying when US mortality rates began to diverge. We use full life tables, for men and women, for 17 high-income countries including the USA. We extract the life expectancy at birth and compute the mortality rates for each 5-year age group from birth up to age 80. Using the metric of how many 'years behind' a country has fallen, we compare US mortality levels with those in other high-income countries ('comparators'). We report life expectancy for 17 high-income countries, for the period 1958-2007. Up to the late 1970s, US men and especially women closely tracked comparators in life expectancy. In the late 1970s in the USA, most strikingly women began to diverge from comparators so that the US female life expectancy in 2007 corresponded to that of the comparators' average 10 years earlier. Mortality rates also began to diverge from the late 1970s, and the largest mortality gap was in the 15-49 age group, for both men and women, where the USA had fallen about 40 years behind the comparators by 2007. Some causes proposed for the relatively high US mortality today-racial differences, lack of universal health insurance, US exceptionalism-changed little while the mortality gap emerged and grew. This suggests that explanations for the growing gap lie elsewhere. Quantification of how many years behind the USA has fallen can help provide clues about where to look for potential causes and remedies.

Nursing professionals have received comprehensive medical education and training. However, whether these medical professionals exhibit positive patient care attitudes and behaviors and thus reduce mortality risks when they themselves are diagnosed with chronic diseases is worth exploring. This study compared the mortality risks of female nurses and general patients with diabetes and elucidated factors that caused this difference. A total of 510,058 female patients newly diagnosed with diabetes between 1998 and 2006 as recorded in the National Health Insurance Research Database were the participants in this study. Nurses with diabetes and general population with diabetes were matched with propensity score method in a 1:10 ratio. The participants were tracked from the date of diagnosis to 2009. The Cox proportional hazards model was utilized to compare the mortality risks in the two groups. Nurses were newly diagnosed with diabetes at a younger age compared with the general public (42.01 ± 12.03 y vs. 59.29 ± 13.11 y). Nevertheless, the matching results showed that nurses had lower mortality risks (HR: 0.53, 95 % CI: 0.38-0.74) and nurses with diabetes in the < 35 and 35-44 age groups exhibited significantly lower mortality risks compared with general patients (HR: 0.23 and 0.36). A further analysis indicated that the factors that influenced the mortality risks of nurses with diabetes included age, catastrophic illnesses, and the severity of diabetes complications. Nurses with diabetes exhibited lower mortality risks possibly because they had received comprehensive medical education and training, may had more knowledge regarding chronic disease control and change their lifestyles. The results can serve as a reference for developing heath education, and for preventing occupational hazards in nurses.

To examine the protective efficacy of measles vaccination in infants in a low income country before 9 months of age. Randomised clinical trial. 1333 infants aged 4.5 months: 441 in treatment group and 892 in control group. Urban area in Guinea-Bissau. Measles vaccination using standard titre Edmonston-Zagreb vaccine at 4.5 months of age. Vaccine efficacy against measles infection, admission to hospital for measles, and measles mortality before standard vaccination at 9 months of age. 28% of the children tested at 4.5 months of age had protective levels of maternal antibodies against measles at enrolment. After early vaccination against measles 92% had measles antibodies at 9 months of age. A measles outbreak offered a unique situation for testing the efficacy of early measles vaccination. During the outbreak, 96 children developed measles; 19% of unvaccinated children had measles before 9 months of age. The monthly incidence of measles among the 441 children enrolled in the treatment arm was 0.7% and among the 892 enrolled in the control arm was 3.1%. Early vaccination with the Edmonston-Zagreb measles vaccine prevented infection; vaccine efficacy for children with serologically confirmed measles and definite clinical measles was 94% (95% confidence interval 77% to 99%), for admissions to hospital for measles was 100% (46% to 100%), and for measles mortality was 100% (-42% to 100%). The number needed to treat to prevent one case of measles between ages 4.5 months and 9 months during the epidemic was 7.2 (6.8 to 9.2). The treatment group tended to have lower overall mortality (mortality rate ratio 0.18, 0.02 to 1.36) although this was not significant. In low income countries, maternal antibody levels against measles may be low and severe outbreaks of measles can occur in infants before the recommended age of vaccination at 9 months. Outbreaks of measles may be curtailed by measles vaccination using the Edmonston-Zagreb vaccine as early as 4.5 months of age. TRIAL REGISTRATION CLINICAL TRIALS: NCT00168558 [ClinicalTrials.gov].

There is debate in the trauma literature regarding the effect of prolonged prehospital transport on morbidity and mortality. This study analyzes the management of hepatic trauma patients requiring surgery and compares the outcomes of the group that was transferred to the University of New Mexico Hospital (UNMH) from outside institutions, to the directly admitted group. The UNMH Trauma Database was queried from 2005-2012. Of 674 patients who sustained liver injuries, 163 required surgery: 46 patients (28.2%) underwent interhospital transfer, and 117 (71.8%) were directly admitted. Variables examined included transfer status, trauma mechanism, transport type, injury severity score (ISS), liver injury grade, and associated injuries. Outcome variables included length of stay (LOS) and 30-day mortality. Outcomes of the transfer group (TG) and direct admit group (DAG) were compared. Both TG and DAG had the same median age (31 y, P = 0.33). The blunt-to-penetrating ratio was the same for each group (48% blunt: 52% penetrating, P = 1.0). Median ISS was 25 for the TG and 26 for the DAG. Grade III or higher injury occurred in 29 (63%) of the TG and in 68 (58%) of the DAG (P = 0.56). Median hospital LOS was 14 d for TG and 9 d for DAG (P = 0.15). Median intensive care unit LOS was 4 d for both groups (P = 0.71). Thirty-day mortality was 20% in each group (P = 0.27). Using a multiple logistic regression model for the outcome of mortality, only age, ISS, and liver injury grade, not transfer status or transport type, had a significant effect on mortality. There was no significant difference in liver injury grade, ISS, LOS, and mortality between TG and DAG. In the patient population of our study, transfer status did not affect outcome.

To enhance the understanding of the current increase in life expectancy and decreasing gender gap in life expectancy. We obtained data on underlying cause of death from the National Board of Health and Welfare in Sweden for 1997 and 2014 and used Arriaga's method to decompose life expectancy by age group and 24 causes of death. Decreased mortality from ischemic heart disease had the largest impact on the increased life expectancy of both men and women and on the decreased gender gap in life expectancy. Increased mortality from Alzheimer's disease negatively influenced overall life expectancy, but because of higher female mortality, it also served to decrease the gender gap in life expectancy. The impact of other causes of death, particularly smoking-related causes, decreased in men but increased in women, also reducing the gap in life expectancy. This study shows that a focus on overall changes in life expectancies may hide important differences in age- and cause-specific mortality. It also emphasizes the importance of addressing modifiable lifestyle factors to reduce avoidable mortality.

Oak decline and related mortality have periodically plagued upland oak-hickory forests, particularly oak species in the red oak group, across the Ozark Highlands of Missouri, Arkansas and Oklahoma since the late 1970s. Advanced tree age and periodic drought, as well as Armillaria root fungi and oak borer attack are believed to contribute to oak decline and mortality....

Suicide among young people aged 10-29 in Sweden.

Hultén, A; Wasserman, D

1992-06-01

This study analyses the incidence of suicide among children and young people aged between 10 and 29 in Sweden, during the period 1974-1986. The study comprises 4,624 individuals whose deaths were the outcome of verified, E950-E959 (n = 3,511) and undetermined, E980-E989 (n = 1,113) suicides. Regression analysis of different age groups separately and all age groups combined shows that the frequency of suicide among children and young people in Sweden did not increase in this period. Nonetheless, mortality figures are high, especially for boys and young men aged 15-29. The maximum suicide-mortality rate (43.2 per 10,000) is noted for young men aged 25-29 in 1984. The male-female ratio with respect to deaths from suicide is 2.5 for the entire group, the smallest difference being in the 15-19 age group (1.7) and the largest in the 25-29 age group (2.8). Methods of committing suicide vary between the sexes and the various age groups. Boys and young men use violent methods more often, and this situation has remained stable throughout the 13-year period. Girls use non-violent methods to a greater extent, but young women aged 18-29 use violent and non-violent methods to almost the same extent. During the 13-year period studied, a change took place in the girls' and young women's choice of methods towards more violent methods in the 1980s compared with the 1970s. Regardless of sex, there are significantly (p less than 0.001) fewer married and more divorced people among those committing suicide compared with corresponding age groups in the overall population.

Background Physical activity (PA) is associated with lower risk for non-communicable diseases and mortality. We aimed to investigate the prospective association between PA and all-cause and cause-specific mortality, and the impact of other potentially contributing factors. Method Data from the community-based Hordaland Health Study (HUSK, 1997–99) were linked to the Norwegian Cause of Death Registry. The study included 20,506 individuals born 1950–1957 and 2,225 born in 1925–1927 (baseline age 40–49 and 70–74). Based on self-report, individuals were grouped as habitually performing low intensity, short duration, low intensity, longer duration or high intensity PA. The hazard ratios (HR) for all-cause and cause-specific mortality during follow-up were calculated. Measures of socioeconomic status, physical health, mental health, smoking and alcohol consumption were added separately and cumulatively to the model. Results PA was associated with lower all-cause mortality in both older (HR 0.75 (95% CI 0.67–0.84)) and younger individuals (HR 0.82 (95% CI 0.72–0.92)) (crude models, HR: risk associated with moving from low intensity, short duration to low intensity, longer duration PA, and from low intensity, longer duration to high intensity). Smoking, education, somatic diagnoses and mental health accounted for some of the association between physical activity and mortality, but a separate protective effect of PA remained in fully adjusted models for cardiovascular (HR 0.78 (95% CI 0.66–0.92)) and respiratory (HR 0.45 (95% CI 0.32–0.63) mortality (both age-groups together), as well as all-cause mortality in the older age group (HR 0.74, 95%CI 0.66–0.83). Conclusion Low intensity, longer duration and high intensity physical activity was associated with reduced all-cause, respiratory and cardiovascular mortality, indicating that physical activity is beneficial also among older individuals, and that a moderate increase in PA can be beneficial.

Alcohol overuse and poverty, each associated with premature death, often exist within disadvantaged neighbourhoods. Cheque cashing places (CCPs) may be opportunistically placed in disadvantaged neighbourhoods, where customers abound. We explored whether neighbourhood density of CCPs and alcohol outlets are each related to premature mortality among adults. Retrospective population-based study. 140 neighbourhoods in Toronto, Ontario, 2005-2009. Adults aged 20-59 years. Our primary outcome was premature all-cause mortality among adults aged 20-59 years. Across neighbourhoods we explored neighbourhood density, in km(2), of CCPs and alcohol outlets, and the relation of each to premature mortality. Poisson regression provided adjusted relative risks (aRRs) and 95% CIs, adjusting for material deprivation quintile (Q), crime Q and number of banks. Intentional self-harm, accidental poisoning and liver disease were among the top five causes of premature death among males aged 20-59 years. The overall premature mortality rate was 96.3/10,000 males and 55.9/10,000 females. Comparing the highest versus lowest CCP density Q, the aRR for death was 1.25 (95% CI 1.15 to 1.36) among males and 1.11 (95% CI 0.99 to 1.24) among females. The corresponding aRR comparing the highest Q versus lowest Q alcohol outlet density in relation to premature mortality was 1.36 (95% CI 1.25 to 1.48) for males and 1.11 (95% CI 1.00 to 1.24) for females. The pattern of the relation between either CCPs or alcohol outlet density and premature mortality was typically J shaped. There is a J-shaped relation between CCP or alcohol outlet density and premature mortality, even on controlling for conventional measures of poverty. Formal banking and alcohol reduction strategies might be added to health promotion policies aimed at reducing premature mortality in highly affected neighbourhoods.

The objective of this study was to investigate the patient characteristics and outcomes in 1406 patients undergoing intra-aortic balloon pump (IABP) counterpulsation. Between 1998 and 2008, 1406 consecutive patients were recorded in a prospective database. Based on the main clinical indication for IABP use, we defined 3 groups: group A, 630 cases of coronary ischaemia or infarction without serious left ventricular (LV) dysfunction; group B, 466 patients with left ventricular failure or cardiogenic shock; group C, 310 patients where IABP was used for miscellaneous procedures such as weaning from cardiopulmonary bypass or during high-risk angioplasty or surgery. Global mortality was 28% (n = 390), with a significant difference between group A (15%, n = 95) and group B (41%, n = 191) (P < 0.001). Mortality in group C was 34% (n = 104). Most insertions were done in the catheterization laboratory (n = 943) with subsequent mortality of 23% whereas 199 balloons were inserted in the operation room with 34% mortality. 170 balloons inserted in the intensive care unit resulted in 46% mortality (P < 0.001). Major IABP-induced complications were 6.8% with no statistical differences between the three groups. Advanced age, left ventricular failure and low BMI were identified as prognostic risk factors for early mortality. IABP deployed at an early clinical stage yields the best results, especially for acute coronary patients with preserved LV function whereas LV failure and late insertion result in worse outcome.

To quantify the contribution of changes in different risk factors population levels and treatment uptake on the decline in CHD mortality in Denmark from 1991 to 2007 in different socioeconomic groups. We used IMPACTSEC, a previously validated policy model using data from different population registries. All adults aged 25-84 years living in Denmark in 1991 and 2007. Deaths prevented or postponed (DPP). There were approximately 11,000 fewer CHD deaths in Denmark in 2007 than would be expected if the 1991 mortality rates had persisted. Higher mortality rates were observed in the lowest socioeconomic quintile. The highest absolute reduction in CHD mortality was seen in this group but the highest relative reduction was in the most affluent socioeconomic quintile. Overall, the IMPACTSEC model explained nearly two thirds of the decline in. Improved treatments accounted for approximately 25% with the least relative mortality reduction in the most deprived quintile. Risk factor improvements accounted for approximately 40% of the mortality decrease with similar gains across all socio-economic groups. The 36% gap in explaining all DPPs may reflect inaccurate data or risk factors not quantified in the current model. According to the IMPACTSEC model, the largest contribution to the CHD mortality decline in Denmark from 1991 to 2007 was from improvements in risk factors, with similar gains across all socio-economic groups. However, we found a clear socioeconomic trend for the treatment contribution favouring the most affluent groups.

Migrant and ethnic minority groups are often assumed to have poor health relative to the majority population. Few countries have the capacity to study a key indicator, mortality, by ethnicity and country of birth. We hypothesized at least 10% differences in mortality by ethnic group in Scotland that would not be wholly attenuated by adjustment for socio-economic factors or country of birth. We linked the Scottish 2001 Census to mortality data (2001-2013) in 4.62 million people (91% of estimated population), calculating age-adjusted mortality rate ratios (RRs; multiplied by 100 as percentages) with 95% confidence intervals (CIs) for 13 ethnic groups, with the White Scottish group as reference (ethnic group classification follows the Scottish 2001 Census). The Scottish Index of Multiple Deprivation, education status, and household tenure were socio-economic status (SES) confounding variables and born in the UK or Republic of Ireland (UK/RoI) an interacting and confounding variable. Smoking and diabetes data were from a primary care sub-sample (about 53,000 people). Males and females in most minority groups had lower age-adjusted mortality RRs than the White Scottish group. The 95% CIs provided good evidence that the RR was more than 10% lower in the following ethnic groups: Other White British (72.3 [95% CI 64.2, 81.3] in males and 75.2 [68.0, 83.2] in females); Other White (80.8 [72.8, 89.8] in males and 76.2 [68.6, 84.7] in females); Indian (62.6 [51.6, 76.0] in males and 60.7 [50.4, 73.1] in females); Pakistani (66.1 [57.4, 76.2] in males and 73.8 [63.7, 85.5] in females); Bangladeshi males (50.7 [32.5, 79.1]); Caribbean females (57.5 [38.5, 85.9]); and Chinese (52.2 [43.7, 62.5] in males and 65.8 [55.3, 78.2] in females). The differences were diminished but not eliminated after adjusting for UK/RoI birth and SES variables. A mortality advantage was evident in all 12 minority groups for those born abroad, but in only 6/12 male groups and 5/12 female groups of those born in the UK/RoI. In the primary care sub-sample, after adjustment for age, UK/RoI born, SES, smoking, and diabetes, the RR was not lower in Indian males (114.7 [95% CI 78.3, 167.9]) and Pakistani females (103.9 [73.9, 145.9]) than in White Scottish males and females, respectively. The main limitations were the inability to include deaths abroad and the small number of deaths in some ethnic minority groups, especially for people born in the UK/RoI. There was relatively low mortality for many ethnic minority groups compared to the White Scottish majority. The mortality advantage was less clear in UK/RoI-born minority group offspring than in immigrants. These differences need explaining, and health-related behaviours seem important. Similar analyses are required internationally to fulfil agreed goals for monitoring, understanding, and improving health in ethnically diverse societies and to apply to health policy, especially on health inequalities and inequities.

Objectives To evaluate trends in premature cancer mortality in Colombia by educational level in three periods: 1998–2002 with low healthcare insurance coverage, 2003–2007 with rapidly increasing coverage and finally 2008–2012 with almost universal coverage (2008–2012). Setting Colombian population-based, national secondary mortality data. Participants We included all (n=188 091) cancer deaths occurring in the age group 20–64 years between 1998 and 2012, excluding only cases with low levels of quality of registration (n=2902, 1.5%). Primary and secondary outcome measures In this descriptive study, we linked mortality data of ages 20–64 years to census data to obtain age-standardised cancer mortality rates by educational level. Using Poisson regression, we modelled premature mortality by educational level estimating rate ratios (RR), relative index of inequality (RII) and the Slope Index of Inequality (SII). Results Relative measures showed increased risks of dying among the lower educated compared to the highest educated; this tendency was stronger in women (RRprimary 1.49; RRsecondary 1.22, both p<0.0001) than in men (RRprimary 1.35; RRsecondary 1.11, both p<0.0001). In absolute terms (SII), cancer caused a difference per 100 000 deaths between the highest and lowest educated of 20.5 in males and 28.5 in females. RII was significantly higher among women and the younger age categories. RII decreased between the first and second periods; afterwards (2008–2012), it increased significantly back to their previous levels. Among women, no significant increases or declines in cancer mortality over time were observed in recent periods in the lowest educated group, whereas strong recent declines were observed in those with secondary education or higher. Conclusions Educational inequalities in cancer mortality in Colombia are increasing in absolute and relative terms, and are concentrated in young age categories. This trend was not curbed by increases in healthcare insurance coverage. Policymakers should focus on improving equal access to prevention, early detection, diagnostic and treatment facilities.

With the advent of the Surgeon General's Report, Healthy People, a renewed interest in and concern for the health-risky practices of the school aged has emerged. Moreover, because the mortality rates for the 15 to 24 year age group continues to increase while the mortality rates for every other age group continues to decline, a school health education imperative has become prevention-based interventions. The experimental, prevention-based alcohol education program reported here describes one such intervention directed at 9th grade students. The program was grounded on the principles of Inoculation Theory and evaluated using a Solomon Four-Group Design. Results indicate that the formulation of preventive alcohol education programs utilizing Inoculation Theory in a school setting is both feasible and productive in achieving designated objectives. Longitudinal assessment of the subjects with regard to their alcohol-related behavior is continuing throughout their high school careers.

To rank the subjects of the Russian Federation by the trend direction in all-cause and cardiovascular mortality (including mortality from coronary heart disease and cerebrovascular diseases) as a whole and at able-bodied age. The investigation used mortality rates from to the 2006 and 2012 data available in the Federal State Statistics Service on 81 subjects of the Russian Federation. According to mortality rates, each region was assigned a rank in 2006 and 2012. Trends in rank changes in the Russian Federation's regions were analyzed. A cluster analysis was used to group the subjects of the Russian Federation by trends in rank changes. The cluster analysis of rank changes from 2006 to 2012 could combine the Russian Federation's regions into 10 groups showing the similar trends in all-cause and circulatory disease mortality rates. Overall, the results of the ranking and further clusterization of the regions of the Russian Federation correspond to the trends in all-cause and cardiovascular mortality rates according to the data of other Russian investigations, by qualitatively complementing them. The trend rank-order method permits a comprehensive comparative analysis of changes in all-cause and cardiovascular mortality in the subjects of the Russian Federation both as a whole and at able-bodied age, which provides qualitatively new information complementing the universally accepted approaches to studying the population's mortality.

Although interest in assessing the impacts of hot temperature and mortality in Hong Kong has increased, less evidence on the effect of cold temperature on mortality is available. We examined both the effects of heat and cold temperatures on daily mortality in Hong Kong for the last decade (2002-2011). A quasi-Poisson model combined with a distributed lag non-linear model was used to assess the non-linear and delayed effects of temperatures on cause-specific and age-specific mortality. Non-linear effects of temperature on mortality were identified. The relative risk of non-accidental mortality associated with cold temperature (11.1 °C, 1st percentile of temperature) relative to 19.4 °C (25th percentile of temperature) was 1.17 (95 % confidence interval (CI): 1.04, 1.29) for lags 0-13. The relative risk of non-accidental mortality associated with high temperature (31.5 °C, 99th percentile of temperature) relative to 27.8 °C (75th percentile of temperature) was 1.09 (95 % CI: 1.03, 1.17) for lags 0-3. In Hong Kong, extreme cold and hot temperatures increased the risk of mortality. The effect of cold lasted longer and greater than that of heat. People older than 75 years were the most vulnerable group to cold temperature, while people aged 65-74 were the most vulnerable group to hot temperature. Our findings may have implications for developing intervention strategies for extreme cold and hot temperatures.

Historical Evolution of Old-Age Mortality and New Approaches to Mortality Forecasting

Knowledge of future mortality levels and trends is important for actuarial practice but poses a challenge to actuaries and demographers. The Lee-Carter method, currently used for mortality forecasting, is based on the assumption that the historical evolution of mortality at all age groups is driven by one factor only. This approach cannot capture an additive manner of mortality decline observed before the 1960s. To overcome the limitation of the one-factor model of mortality and to determine the true number of factors underlying mortality changes over time, we suggest a new approach to mortality analysis and forecasting based on the method of latent variable analysis. The basic assumption of this approach is that most variation in mortality rates over time is a manifestation of a small number of latent variables, variation in which gives rise to the observed mortality patterns. To extract major components of mortality variation, we apply factor analysis to mortality changes in developed countries over the period of 1900–2014. Factor analysis of time series of age-specific death rates in 12 developed countries (data taken from the Human Mortality Database) identified two factors capable of explaining almost 94 to 99 percent of the variance in the temporal changes of adult death rates at ages 25 to 85 years. Analysis of these two factors reveals that the first factor is a “young-age” or background factor with high factor loadings at ages 30 to 45 years. The second factor can be called an “oldage” or senescent factor because of high factor loadings at ages 65 to 85 years. It was found that the senescent factor was relatively stable in the past but now is rapidly declining for both men and women. The decline of the senescent factor is faster for men, although in most countries, it started almost 30 years later. Factor analysis of time series of age-specific death rates conducted for the oldest-old ages (65 to 100 years) found two factors explaining variation of mortality at extremely old ages in the United States. The first factor is comparable to the senescent factor found for adult mortality. The second factor, however, is specific to extreme old ages (96 to 100 years) and shows peaks in 1960 and 2000. Although mortality below 90 to 95 years shows a steady decline with time driven by the senescent factor, mortality of centenarians does not decline and remains relatively stable. The approach suggested in this paper has several advantages. First, it is able to determine the total number of independent factors affecting mortality changes over time. Second, this approach allows researchers to determine the time interval in which underlying factors remain stable or undergo rapid changes. Most methods of mortality projections are not able to identify the best base period for mortality projections, attempting to use the longest-possible time period instead. We observe that the senescent factor of mortality continues to decline, and this decline does not demonstrate any indications of slowing down. At the same time, mortality of centenarians does not decline and remains stable. The lack of mortality decline at extremely old ages may diminish anticipated longevity gains in the future.

Racial differences in colorectal cancer mortality. The importance of stage and socioeconomic status.

PubMed

Marcella, S; Miller, J E

2001-04-01

This investigation studies racial and socioeconomic differences in mortality from colorectal cancer, and how they vary by stage and age at diagnosis. Cox proportional hazards models were used to estimate the hazard ratio of dying from colorectal cancer, controlling for tumor characteristics and sociodemographic factors. Black adults had a greater risk of death from colorectal cancer, especially in early stages. The gender gap in mortality is wider among blacks than whites. Differences in tumor characteristics and socioeconomic factors each accounted for approximately one third of the excess risk of death among blacks. Effects of socioeconomic factors and race varied significantly by age. Higher stage-specific mortality rates and more advanced stage at diagnosis both contribute to the higher case-fatality rates from colorectal cancer among black adults, only some of which is due to socioeconomic differences. Socioeconomic and racial factors have their most significant effects in different age groups.

Rollover car crashes (ROCs) are serious public safety concerns worldwide. Objective. To determine the incidence and outcomes of ROCs with or without ejection of occupants in the State of Qatar. Methods. A retrospective study of all patients involved in ROCs admitted to Level I trauma center in Qatar (2011-2012). Patients were divided into Group I (ROC with ejection) and Group II (ROC without ejection). Results. A total of 719 patients were evaluated (237 in Group I and 482 in Group II). The mean age in Group I was lower than in Group II (24.3 ± 10.3 versus 29 ± 12.2; P = 0.001). Group I had higher injury severity score and sustained significantly more head, chest, and abdominal injuries in comparison to Group II. The mortality rate was higher in Group I (25% versus 7%; P = 0.001). Group I patients required higher ICU admission rate (P = 0.001). Patients in Group I had a 5-fold increased risk for age-adjusted mortality (OR 5.43; 95% CI 3.11–9.49), P = 0.001). Conclusion. ROCs with ejection are associated with higher rate of morbidity and mortality compared to ROCs without ejection. As an increased number of young Qatari males sustain ROCs with ejection, these findings highlight the need for research-based injury prevention initiatives in the country. PMID:24693231

Objectives To investigate the effect of job demand, job control and job strain on total mortality among white-collar and blue-collar employees working in the public sector. Design 28-year prospective population-based follow-up. Setting Several municipals in Finland. Participants 5731 public sector employees from the Finnish Longitudinal Study on Municipal Employees Study aged 44–58 years at baseline. Outcomes Total mortality from 1981 to 2009 among individuals with complete data on job strain in midlife, categorised according to job demand and job control: high job strain (high job demands and low job control), active job (high job demand and high job control), passive job (low job demand and low job control) and low job strain (low job demand and high job control). Results 1836 persons died during the follow-up. Low job control among men increased (age-adjusted HR 1.26, 95% CI 1.12 to 1.42) and high job demand among women decreased the risk for total mortality HR 0.82 (95% CI 0.71 to 0.95). Adjustment for occupational group, lifestyle and health factors attenuated the association for men. In the analyses stratified by occupational group, high job strain increased the risk of mortality among white-collar men (HR 1.52, 95% CI 1.09 to 2.13) and passive job among blue-collar men (HR 1.28, 95% CI 1.05 to 1.47) compared with men with low job strain. Adjustment for lifestyle and health factors attenuated the risks. Among white-collar women having an active job decreased the risk for mortality (HR 0.78, 95% CI 0.60 to 1.00). Conclusion The impact of job strain on mortality was different according to gender and occupational group among middle-aged public sector employees. PMID:22422919

The decision to proceed with digital replantation in the elderly can be challenging. In addition to success of the replanted part, perioperative morbidity and mortality must be considered. The purpose of this study was to compare adverse events in patients less than 65 years of age compared with those 65 years and older after digital replantation. We hypothesize that there is an increased incidence of mortality and sentinel adverse events in patients aged 65 and older. We obtained data from the Nationwide Inpatient Sample over a 10-year period from 1998 to 2007. Replantation was identified using International Classification of Diseases-9 procedure codes for finger and thumb reattachment (84.21 and 84.22). Adverse events were identified using Patient Safety Indicators (PSI) to identify adverse events occurring during hospitalization. We used the Charlson index to study medical comorbidities and bivariate statistics. During the study period 15,413 finger and thumb replantations were performed in the United States, with 616 performed on patients age 65 and older. The overall in-hospital mortality was 0.04% with no statistical difference when factoring age. For the entire group, the percentage of PSI was 0.6%, the most common being postoperative deep venous thrombosis and pulmonary embolus. Overall, there was no difference in PSI between the 2 groups. The older group had a higher rate of transfusion, 4% versus 8% (p < .05) and were more likely to have a nonroutine disposition (ie, nursing home) (p < .001). We found no correlation between the Charlson index and PSI. This study found no difference in sentinel perioperative complications or mortality when comparing replantation patients under 65 years of age and those age 65 and older. Age alone should not be an absolute contraindication to finger replantation. Instead, the patient's functional demands, type of injury, general state of health, and rehabilitative potential should drive the decision of whether to proceed with replantation.

The aim of this study is to explore incidence and incidence-based mortality trends for endometrial cancer in the USA and project future incident cases, accounting for differences by race and histological subtype. Data on age-adjusted and age-specific incidence and mortality rates of endometrial cancer were obtained from the Surveillance, Epidemiology, and End Results 18 registries. Trends in rates were analyzed using Joinpoint regression, and average annual percent change (AAPC) in recent years (2006-2011) was computed for histological subtypes by race. Age, histological, and race-specific rates were applied to US Census Bureau population census estimates to project new cases from 2015 to 2040, accounting for observed AAPC trends, which were progressively attenuated for the future years. The annual number of cases is projected to increase substantially from 2015 to 2040 across all racial groups. Considerable variation in incidence and mortality trends was observed both between and within racial groups when considering histology. As the US population undergoes demographic changes, incidence of endometrial cancer is projected to rise. The increase will occur in all racial groups, but larger increases will be seen in aggressive histology subtypes that disproportionately affect black women.

ABSTRACT OBJECTIVE To estimate the potential years of life lost by road traffic injuries three years after the beginning of the Decade of Action for Traffic Safety. METHODS We analyzed the data of the Sistema de Informações sobre Mortalidade (SIM – Mortality Information System) related to road traffic injuries, in 2013. We estimated the crude and standardized mortality rates for Brazil and geographic regions. We calculated, for the Country, the proportional mortality according to age groups, education level, race/skin color, and type or quality of the victim while user of the public highway. We estimated the potential years of life lost according to sex. RESULTS The mortality rate in 2013 was of 21.0 deaths per 100,000 inhabitants for the Country. The Midwest region presented the highest rate (29.9 deaths per 100,000 inhabitants). Most of the deaths by road traffic injuries took place with males (34.9 deaths per 100,000 males). More than half of the people who have died because of road traffic injuries were of black race/skin color, young adults (24.2%), individuals with low schooling (24.0%), and motorcyclists (28.5%). The mortality rate in the triennium 2011-2013 decreased 4.1%, but increased among motorcyclists. Across the Country, more than a million of potential years of life were lost, in 2013, because of road traffic injuries, especially in the age group of 20 to 29 years. CONCLUSIONS The impact of the high mortality rate is of over a million of potential years of life lost by road traffic injuries, especially among adults in productive age (early mortality), in only one year, representing extreme social cost arising from a cause of death that could be prevented. Despite the reduction of mortality by road traffic injuries from 2011 to 2013, the mortality rates increased among motorcyclists. PMID:27706375

We carried out an evaluation of a large-scale New Zealand retrofit programme using administrative data that provided the statistical power to assess the effect of insulation and/or heating retrofits on cardiovascular and respiratory-related mortality in people aged 65 and over with prior respiratory or circulatory hospitalisations. Quasi-experimental cohort study based on administrative data. New Zealand. From a larger study cohort of over 900 000 people, we selected two subcohorts: 3287 people who were aged 65 and over and had experienced pretreatment period cardiovascular-related hospitalisation (ICD-10 chapter 9), and 1561 people aged 65 and over who had experienced pretreatment respiratory-related hospitalisation (ICD-10 chapter 10). Treatment group individuals lived in a home that received insulation and/or heating retrofits under the Warm Up New Zealand: Heat Smart programme. Control group individuals lived in a home that was matched to a treatment home based on physical characteristics and location. HR for all-cause mortality for treatment with insulation, heating, or insulation and heating relative to control group. People with pretreatment circulatory hospitalisation who occupied a household that received only insulation had an HR for all-cause mortality of 0.673 (95% CI 0.535 to 0.847) (p<0.001) relative to control group members. Individuals with a pretreatment respiratory hospitalisation who occupied a household that received only an insulation retrofit had an HR for all-cause mortality of 0.830 (95% CI 0.655 to 1.051) (p=0.122) relative to control group members. There was no evidence of an additional benefit from receiving heating. We interpret the hazard rate observed for cardiovascular subcohort individuals who received insulation as evidence of a protective effect, reducing the risk of mortality for vulnerable older adults. There is suggestive evidence of a protective effect of insulation for the respiratory subcohort. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

This study sought to describe the total mortality trend by socioeconomic deprivation (SED) in the Madrid Autonomous Region, by sex and age group. Cross-sectional ecological study by census tract, in two periods: 1994-2000 (P1) with SED of 1996 census and 2001-07 (P2) with SED of 2001 census. We calculated the relative risks (RRs) and their 95% credibility intervals (95% CIs) by SED quintile (Q), taking the quintile of least deprivation as reference. Besag-York-Mollié ecological regression models and the Integrated Nested Laplace Approximation procedure were applied. The absolute differences in age-standardized rates were compared by SED quintile. Inequalities decreased in young adults: among men aged 20-39 years, the RR in Q5 versus Q1 ranged from 2.73 (95% CI, 2.51-3.02) in P1 to 1.93 (95% CI, 1.76-2.15) in P2, due to the greater improvement in the most underprivileged groups. In contrast, there was an increase in SED-related mortality in the 40-79 age group. Among men aged 40-59 years, the RR in Q5 versus Q1 rose from 1.88 (95% CI, 1.76-2.02) in P1 to 2.29 (95% CI, 2.17-2.43) in P2; the improvement was greater in the most privileged groups. In a context of an economic boom, inequalities were observed to increase among adults by a greater improvement in the most privileged groups. © The Author 2015.

People with a lower socioeconomic position have a higher the prevalence of most self-rated health problems. In this article we ask whether this may be attributed to self-rated health not reflecting actual health, understood as mortality, in different socioeconomic groups. For the study we used data from the Nord-Trøndelag Health Study 1984-86 (HUNT1), in which the county's entire adult population aged 20 years and above were invited to participate. The association between self-rated health and mortality in different occupational classes and income groups was analysed. The analysis corrected for age, chronic disease, functional impairment and lifestyle factors. The association between self-rated health and mortality was of the same order of magnitude for the occupational classes and income groups, but persons without work/income and with poor self-rated health stood out. Compared with persons in the highest socioeconomic class, unemployed men had a hazard ratio for death that was three times higher in the follow-up period. For women with no income, the ratio was twice as high. INTERPRETATION Self-rated health and mortality largely conform to the different socioeconomic strata. This supports the perception that socioeconomic differences in health are a reality and represent a significant challenge nationally. Our results also increase the credibility of findings from other studies that use self-reported health in surveys to measure differences and identify the mechanisms that create them.

Randomized trials have shown that measles vaccine (MV) prevents nonmeasles deaths. MV campaigns are conducted to eliminate measles infection. The overall mortality effect of MV campaigns has not been studied. Bandim Health Project (BHP) surveys children aged 0-4 years in rural Guinea-Bissau through a health and demographic surveillance system. A national MV campaign in 2006 targeted children aged 6 months to 15 years. In a Cox proportional hazards model with age as the underlying timescale, we compared mortality of children aged 6-59 months after the campaign with mortality in the same age group during the 2 previous years. Eight thousand one hundred fifty eight children aged 6-59 months were under BHP surveillance during the 2006 campaign and 7999 and 8108 during similar periods in 2004 and 2005. At least 90% of the eligible children received MV in the campaign. There were 161 nonaccident deaths in 12 months after the campaign compared with 203 and 206 deaths in the 2 previous years, the adjusted mortality rate ratio (aMRR) comparing all children in 2006 with all children in 2004 to 2005 being 0.80 (95% confidence interval: 0.66-0.96). Censoring deaths caused by measles infection, the aMRR was 0.83 (0.69-1.00). The mortality reduction was separately significant for girls [aMRR = 0.74 (0.56-0.97)] and for children who also had received routine MV [MRR = 0.59 (0.36-0.99)]. Mortality levels were stable during 2004 and 2005, but a significant drop occurred after the 2006 MV campaign and was not explained by the prevention of measles deaths. If MV campaigns reduce nonmeasles-related mortality, the policies for measles vaccination should take this into account.

Smoking habits do not seem to be the main explanation of the epidemiological characteristics of female lung cancer mortality in Asian countries. However, Asian countries are often excluded from studies of geographical differences in trends for lung cancer mortality. We thus examined lung cancer trends from 1971 to 1995 among men and women for 23 countries, including four in Asia. International and national data were used to analyze lung cancer mortality from 1971 to 1995 in both sexes. Age-standardized mortality rates (ASMR) were analyzed in five consecutive five-year periods and for each five-year age group in the age range 30 to 79. The age-period-cohort (APC) model was used to estimate the period effect (adjusted for age and cohort effects) for mortality from lung cancer. The sex ratio of the ASMR for lung cancer was lower in Asian countries, while the sex ratio of smoking prevalence was higher in Asian countries. The mean values of the sex ratio of the ASMR from lung cancer in Taiwan, Hong Kong, Singapore, and Japan for the five 5-year period were 2.10, 2.39, 3.07, and 3.55, respectively. These values not only remained quite constant over each five-year period, but were also lower than seen in the western countries. The period effect, for lung cancer mortality as derived for the 23 countries from the APC model, could be classified into seven patterns. Period effects for both men and women in 23 countries, as derived using the APC model, could be classified into seven patterns. Four Asian countries have a relatively low sex ratio in lung cancer mortality and a relatively high sex ratio in smoking prevalence. Factors other than smoking might be important, especially for women in Asian countries.

Lower intelligence early in life is associated with increased risks for coronary heart disease (CHD) and mortality. Intelligence level might affect compliance to treatment but its prognostic importance in patients with CHD is unknown. A cohort of 1923 Swedish men with a measure of intelligence from mandatory military conscription in 1969-1970 at age 18-20, who were diagnosed with CHD 1991-2007, were followed to the end of 2008. recurrent CHD event. Secondary outcome: case fatality from the first event, cardiovascular and all-cause mortality. National registers provided information on CHD events, comorbidity, mortality and socioeconomic factors. The fully adjusted HRs for recurrent CHD for medium and low intelligence, compared with high intelligence, were 0.98, (95% CIs 0.83 to 1.16) and 1.09 (0.89 to 1.34), respectively. The risks were increased for cardiovascular and all-cause mortality with lower intelligence, but were attenuated in the fully adjusted models (fully adjusted HRs for cardiovascular mortality 1.92 (0.94 to 3.94) and 1.98 (0.89 to 4.37), respectively; for all-cause mortality 1.63 (1.00 to 2.65) and 1.62 (0.94 to 2.78), respectively). There was no increased risk for case-fatality at the first event (fully adjusted ORs 1.06 (0.73 to 1.55) and 0.97 (0.62 to 1.50), respectively). Although we found lower intelligence to be associated with increased mortality in middle-aged men with CHD, there was no evidence for its possible effect on recurrence in CHD.

The Gulf Cooperation Council (GCC) countries namely, Bahrain, Kuwait, Oman, Qatar, United Arab Emirates (UAE), and Saudi Arabia, have experienced unique demographic changes. The major population growth contributor in these countries is young migrants, which has led to a shift in the population age pyramid. Migrants constitute the vast proportion of GCC countries' population reaching >80% in Qatar and UAE. Using Global Burden of Disease Study 2015 (GBD 2015) and United Nations data, for the GCC countries, we assessed the association between age-standardized mortality and population size trends with linear and polynomial regressions. In 1990-2015, all-cause age-standardized mortality was inversely proportional to national population size (p-values: 0.0001-0.0457). In Bahrain, Qatar, Oman, and Saudi Arabia, the highest annual decrease in mortality was observed when the annual population growth was the highest. In Qatar, all-cause age-specific mortality was inversely proportional to age-specific population size. This association was statistically significant among the 5-14 and 15-49 age groups, which have the largest population size. Cause-specific age-standardized mortality was also inversely proportional to population size. This association was statistically significant for half of the GBD 2015-defined causes of death such as "cirrhosis and other chronic liver diseases" and "HIV/AIDS and tuberculosis". Remarkably, incoming migrants to Qatar have to be negative for HIV, hepatitis B and C, and tuberculosis. These results show that decline in mortality can be partly attributed to the increase in GCC countries' population suggesting a healthy migrant effect that influences mortality rates. Consequently, benefits of health interventions and healthcare improvement are likely to be exaggerated in such countries hosting a substantial proportion of migrants compared with countries where migration is low. Researchers and policymakers should be cautious to not exclusively attribute decline in mortality within the GCC countries as a result of the positive effects of health interventions or healthcare improvement.

The Gulf Cooperation Council (GCC) countries namely, Bahrain, Kuwait, Oman, Qatar, United Arab Emirates (UAE), and Saudi Arabia, have experienced unique demographic changes. The major population growth contributor in these countries is young migrants, which has led to a shift in the population age pyramid. Migrants constitute the vast proportion of GCC countries’ population reaching >80% in Qatar and UAE. Using Global Burden of Disease Study 2015 (GBD 2015) and United Nations data, for the GCC countries, we assessed the association between age-standardized mortality and population size trends with linear and polynomial regressions. In 1990–2015, all-cause age-standardized mortality was inversely proportional to national population size (p-values: 0.0001–0.0457). In Bahrain, Qatar, Oman, and Saudi Arabia, the highest annual decrease in mortality was observed when the annual population growth was the highest. In Qatar, all-cause age-specific mortality was inversely proportional to age-specific population size. This association was statistically significant among the 5–14 and 15–49 age groups, which have the largest population size. Cause-specific age-standardized mortality was also inversely proportional to population size. This association was statistically significant for half of the GBD 2015-defined causes of death such as “cirrhosis and other chronic liver diseases” and “HIV/AIDS and tuberculosis”.

Mortality rates were examined for Boston women, aged 15 to 44, from 1980 to 1989. There were 1234 deaths, with a rate of 787.8/100,000 for the decade. Leading causes were cancer, accidents, heart disease, homicide, suicide, and chronic liver disease. After age adjustment, African-American women in this age group were 2.3 times more likely to die than White women. Deaths at least partly attributable to smoking and alcohol amounted to 29.8% and 31.9%, respectively. Mortality was found to be related more directly to the general well-being of young women than to their reproductive status, and many deaths were preventable. African-American/White disparities were most likely linked to social factors. These findings suggest that health needs of reproductive-age women transcend reproductive health and require comprehensive interventions.

Exacerbation of chronic obstructive pulmonary disease (COPD) is an important cause of morbidity and mortality, but the effect of metabolic compensation of respiratory acidosis (RA) on mortality is not fully understood. To investigate the relationship between metabolic compensation and mortality in COPD patients with RA. We prospectively investigated all COPD patients with RA admitted to the respiratory intensive care unit between February 2001 and March 2007. Two hundred and thirteen patients (159 male, 54 female; mean age 65 +/- 10.8 years) were divided into three groups (71 patients each) according to base excess (BE) levels: (1) low BE, (2) medium BE, and (3) high BE. H(+) concentration was calculated according to their standard formula and BE was calculated according to the Van Slyke equation. The overall mortality rate was 24.9%. The group mortality rates were 32, 17 and 25% in the low, medium and high BE groups, respectively (p = 0.001). When patients were divided into three groups according to the HCO(3)(-) levels, the group mortality rate was 59.1% in the low HCO(3)(-) group and 19.8% in the high HCO(3)(-) group. Based on univariate analysis, six factors affecting mortality were identified. However, multivariate analysis showed that the levels of serum HCO(3)(-) (p = 0.013; OR: 0.552; CI: 0.345-0.882) and creatinine (p = 0.019; OR: 2.114; CI: 1.132-3.949) had an independent effect. In patients with COPD exacerbation and hypercapnia, the development of sufficient metabolic compensation and adequate renal function significantly decreases mortality. Copyright 2008 S.

Background Ample evidence has shown that early-life social conditions are associated with mortality later in life. However, little attention has been given to the strength of these effects across specific age intervals from birth to old age. In this paper, we study the effect of the family's socioeconomic position and mother's marital status at birth on all-cause mortality at different age intervals in a Swedish cohort of 11 868 individuals followed across their lifespan. Methods Using the Uppsala Birth Cohort Multigenerational Study, we fitted Cox regression models to estimate age-varying HRs of all-cause mortality according to mother's marital status and family's socioeconomic position. Results Mother's marital status and family's socioeconomic position at birth were associated with higher mortality rates throughout life (HR 1.18 (95% CI 1.12 to 1.26) for unmarried mothers; 1.19 (95% CI 1.12 to 1.25) for low socioeconomic position). While the effect of family's socioeconomic position showed little variation across different age groups, the effect of marital status was stronger for infant mortality (HR 1.47 (95% CI 1.23 to 1.76); p=0.04 for heterogeneity). The results remained robust when early life and adult mediator variables were included. Conclusions Family's socioeconomic position and mother's marital status involve different dimensions of social stratification with independent effects on mortality throughout life. Our findings support the importance of improving early-life conditions in order to enhance healthy ageing. PMID:26733672

To determine the efficacy and tolerability of β blockers in a broad age range of women and men with heart failure with reduced ejection fraction (HFrEF) by pooling individual patient data from placebo controlled randomised trials. Prospectively designed meta-analysis of individual patient data from patients aged 40-85 in sinus rhythm at baseline, with left ventricular ejection fraction <0.45. 13,833 patients from 11 trials; median age 64; 24% women. The primary outcome was all cause mortality; the major secondary outcome was admission to hospital for heart failure. Analysis was by intention to treat with an adjusted one stage Cox proportional hazards model. Compared with placebo, β blockers were effective in reducing mortality across all ages: hazard ratios were 0.66 (95% confidence interval 0.53 to 0.83) for the first quarter of age distribution (median age 50); 0.71 (0.58 to 0.87) for the second quarter (median age 60); 0.65 (0.53 to 0.78) for the third quarter (median age 68); and 0.77 (0.64 to 0.92) for the fourth quarter (median age 75). There was no significant interaction when age was modelled continuously (P=0.1), and the absolute reduction in mortality was 4.3% over a median follow-up of 1.3 years (number needed to treat 23). Admission to hospital for heart failure was significantly reduced by β blockers, although this effect was attenuated at older ages (interaction P=0.05). There was no evidence of an interaction between treatment effect and sex in any age group. Drug discontinuation was similar regardless of treatment allocation, age, or sex (14.4% in those give β blockers, 15.6% in those receiving placebo). Irrespective of age or sex, patients with HFrEF in sinus rhythm should receive β blockers to reduce the risk of death and admission to hospital.Registration PROSPERO CRD42014010012; Clinicaltrials.gov NCT00832442.

2017-12-01

Over the past decade, the number of patients on dialysis and with cardiovascular diseases has steadily increased. This retrospective analysis compares the postoperative mortality after cardiac surgery between patients on hemodialysis and peritoneal dialysis. Between 1998 and 2015, 136 patients with end-stage renal disease initiating dialysis more than one month before surgery underwent cardiac surgery. Demographics, preoperative hemodynamic and biochemical data were collected from the patient records. Vital status and date of death was retrieved from a national register. Hemodialysis was undertaken in 73% and peritoneal dialysis in 22% of patients aged 59.7 ± 12.9 years, mean EuroSCORE 8.6% ± 3.5. Isolated coronary artery bypass graft was performed in 46%, isolated valve procedure in 29% and combined procedures in 24% with no significant statistical difference between groups. The 30-day mortality was 14% for hemodialysis patients and 3% for peritoneal dialysis patients (p = .056). One-year and 5-year mortality were, 30% and 59% in the hemodialysis group, 30% and 57% in the peritoneal dialysis group (p = .975, p = .852). Independent predictors of total mortality were age (p = .001), diabetes (p = .017) and active endocarditis (p = .012). No statistically significant difference in mortality was found between patients in hemo- or peritoneal dialysis. However, we observed that patients with end-stage renal disease on dialysis have two times higher mortality rate than estimated by EuroSCORE.

Objective The best practice tariff (BPT) incentivizes hospitals in the England and Wales National Health Service to provide multiprofessional care to patients with hip fractures. The initial six targets included: 1) admission under consultant-led joint orthopedic–geriatric care, 2) multidisciplinary assessment protocol on admission, 3) surgery within 36 hours, 4) geriatrician review within 72 hours, 5) multiprofessional rehabilitation, and 6) assessment for falls and bone protection. We aimed to examine the relationship between BPT achievement and important patient outcomes and whether the BPT could predict these independently of other validated predictors. Materials and methods A retrospective review was conducted on 516 patient episodes. Four outcomes were defined: 1) 30-day mortality, 2) 365-day mortality, 3) postoperative length of stay on trauma ward (LOS-T), and 4) total post-operative hospital LOS (LOS-H). Patient episodes were grouped as follows: 1) group 1, pre-BPT, 2) group 2, BPT achievers, 3) group 3, BPT fails. These were compared for mortality (χ2 test) and for LOS (Kruskal–Wallis test). Event analysis was done for groups 2 and 3 using generalized linear modeling, with age, sex, American Society of Anesthesiologists grade, hemoglobin, albumin, creatinine, and BPT achievement evaluated as predictors. Results The three groups did not differ significantly in baseline characteristics or outcomes. In the event analysis, the risk of 30-day mortality was related only to abnormal creatinine (P=0.025); mortality at 365 days was related significantly to low albumin (P=0.023) and weakly to abnormal creatinine (P=0.089). The risks of both increased LOS-T and LOS-H were related to age only (P=0.052, P<0.001, respectively). Conclusion Achieving BPT does not predict any outcome of interest on its own. PMID:25489240

The aim of this study was to identify the frequency and prevalence of comorbidities in sarcoid patients and to assess their influence on overall mortality in the cohort of patients with sarcoidosis. A cohort of 557 patients with histologically confirmed sarcoidosis diagnosed between 2007 and 2011 and a group of non-sarcoid controls were observed. All patients were carefully observed for comorbidities and mortality. 291 males (52.2%) and 266 females (47.8%) with mean age 48.4 ± 12.0 years in sarcoidosis group and a group of 100 controls with mean age (49.25 ± 10.3) were observed. The mean number of comorbidities in both groups was similar (0.9 ± 0.99 vs 0.81 ± 0.84 NS). The frequency of thyroid disease was significantly higher in sarcoidosis group comparing to controls at the time of diagnosis (OR = 3.62 P = 0.0144). During the observation period (median 58.0 months), 16 patients died (2.9%). The mean number of comorbidities was significantly higher in the groups of non-survivors as compared to survivors (2.8 ± 1.0, vs 0.8 ± 0.9), P < 0.0001. The comorbidity burden has strong impact on mortality in sarcoidosis. Thyroid diseases are more frequent in sarcoidosis than in non-sarcoid controls. © 2015 John Wiley & Sons Ltd.

Ample studies have observed an adverse association between individual socioeconomic position (SEP) and lung cancer mortality. Moreover, the presence of a partner has shown to be a crucial determinant of health. Yet, few studies have assessed whether partner's SEP affects health in addition to individual SEP. This paper will study whether own SEP (education), partner's SEP (partner's education) and own and partner's SEP combined (housing conditions), are associated with lung cancer mortality in Belgium. Data consist of the Belgian 2001 census linked to register data on cause-specific mortality for 2001-2011. The study population includes all married or cohabiting Belgian inhabitants aged 40-84 years. Age-standardized lung cancer mortality rates (direct standardization) and mortality rate ratios (Poisson regression) were computed for the different SEP groups. In men, we observed a clear inverse association between all SEP indicators (own and partner's education, and housing conditions) and lung cancer mortality. Men benefit from having a higher educated partner in terms of lower lung cancer mortality rates. These observations hold for both middle-aged and older men. For women, the picture is less uniform. In middle-aged and older women, housing conditions is inversely associated with lung cancer mortality. As for partner's education, for middle-aged women, the association is rather weak whereas for older women, there is no such association. Whereas the educational level of middle-aged women is inversely associated with lung cancer mortality, in older women this association disappears in the fully adjusted model. Both men and women benefit from being in a relationship with a high-educated partner. It seems that for men, the educational level of their partner is of great importance while for women the housing conditions is more substantial. Both research and policy interventions should allow for the family level as well.

Mortality Risk in Pediatric Motor Vehicle Crash Occupants: Accounting for Developmental Stage and Challenging Abbreviated Injury Scale Metrics.

Survival risk ratios (SRRs) and their probabilistic counterpart, mortality risk ratios (MRRs), have been shown to be at odds with Abbreviated Injury Scale (AIS) severity scores for particular injuries in adults. SRRs have been validated for pediatrics but have not been studied within the context of pediatric age stratifications. We hypothesized that children with similar motor vehicle crash (MVC) injuries may have different mortality risks (MR) based upon developmental stage and that these MRs may not correlate with AIS severity. The NASS-CDS 2000-2011 was used to define the top 95% most common AIS 2+ injuries among MVC occupants in 4 age groups: 0-4, 5-9, 10-14, and 15-18 years. Next, the National Trauma Databank 2002-2011 was used to calculate the MR (proportion of those dying with an injury to those sustaining the injury) and the co-injury-adjusted MR (MRMAIS) for each injury within 6 age groups: 0-4, 5-9, 10-14, 15-18, 0-18, and 19+ years. MR differences were evaluated between age groups aggregately, between age groups based upon anatomic injury patterns and between age groups on an individual injury level using nonparametric Wilcoxon tests and chi-square or Fisher's exact tests as appropriate. Correlation between AIS and MR within each age group was also evaluated. MR and MRMAIS distributions of the most common AIS 2+ injuries were right skewed. Aggregate MR of these most common injuries varied between the age groups, with 5- to 9-year-old and 10- to 14-year-old children having the lowest MRs and 0- to 4-year-old and 15- to 18-year-old children and adults having the highest MRs (all P <.05). Head and thoracic injuries imparted the greatest mortality risk in all age groups with median MRMAIS ranging from 0 to 6% and 0 to 4.5%, respectively. Injuries to particular body regions also varied with respect to MR based upon age. For example, thoracic injuries in adults had significantly higher MRMAIS than such injuries among 5- to 9-year-olds and 10- to 14-year-olds (P =.04; P <.01). Furthermore, though AIS was positively correlated with MR within each age group, less correlation was seen for children than for adults. Large MR variations were seen within each AIS grade, with some lower AIS severity injuries demonstrating greater MRs than higher AIS severity injuries. As an example, MRMAIS in 0- to 18-year-olds was 0.4% for an AIS 3 radius fracture versus 1.4% for an AIS 2 vault fracture. Trauma severity metrics are important for outcome prediction models and can be used in pediatric triage algorithms and other injury research. Trauma severity may vary for similar injuries based upon developmental stage, and this difference should be reflected in severity metrics. The MR-based data-driven determination of injury severity in pediatric occupants of different age cohorts provides a supplement or an alternative to AIS severity classification for pediatric occupants in MVCs.

Trends in mortality differentials and life expectancy for male social security-covered workers, by socioeconomic status.

PubMed

Waldron, Hilary

2007-01-01

This article presents an analysis of trends in mortality differentials and life expectancy by average relative earnings for male Social Security-covered workers aged 60 or older. Because average relative earnings are measured at the peak of the earnings distribution (ages 45-55), it is assumed that they act as a rough proxy for socioeconomic status. The historical literature reviewed in this analysis generally indicates that mortality differentials by socioeconomic status have not been constant over time. For this study, time trends are examined by observing how mortality differentials by average relative earnings have been changing over 29 years of successive birth cohorts that encompass roughly the first third of the 20th century. Deaths for these birth cohorts are observed at ages 60-89 from 1972 through 2001, encompassing roughly the last third of the 20th century. The large size and long span of death observations allow for disaggregation by age and year-of-birth groups in the estimation of mortality differentials by socioeconomic status. This study finds a difference in both the level and the rate of change in mortality improvement over time by socioeconomic status for male Social Security-covered workers. Average relative earnings (measured as the relative average positive earnings of an individual between ages 45 and 55) are used as a proxy for adult socioeconomic status. In general, for birth cohorts spanning the years 1912-1941 (or deaths spanning the years 1972-2001 at ages 60-89), the top half of the average relative earnings distribution has experienced faster mortality improvement than has the bottom half. Specifically, male Social Security-covered workers born in 1941 who had average relative earnings in the top half of the earnings distribution and who lived to age 60 would be expected to live 5.8 more years than their counterparts in the bottom half. In contrast, among male Social Security-covered workers born in 1912 who survived to age 60, those in the top half of the earnings distribution would be expected to live only 1.2 years more than those in the bottom half. The life expectancy estimates in this article represent one possible outcome under one set of assumptions. These projections should not be regarded as an accurate depiction of the future. Specifically, this study adopts a simple projection method in which differentials are assumed to follow the pattern observed over the last 30 years of the 20th century for the first 30 years of the 21st century. This assumption lacks theoretical underpinnings because the causes of the widening differentials observed over the past 30 years have not been determined. On the one hand, if the trend of widening mortality differentials by year of birth observed over the past 30 years does not continue, the projection method used in this analysis could lead to an overestimation of future differences in life expectancy between socioeconomic groups. On the other hand, if mortality differentials do not narrow by age as observed in the past, the projection method used could lead to an underestimation of the differences in life expectancy between socioeconomic groups aged 60 or older.

This study aims to characterize the heterogeneity in BMI trajectories and evaluate how different BMI trajectories predict mortality risk in Canadian seniors. Data came from the Canadian National Population Health Survey (NPHS, 1994-2011) and 1480 individuals aged 65-79 years with at least four BMI records were included in this study. Group-based trajectory model was used to identify distinct subgroups of longitudinal trajectories of BMI measured over 19 years for men and women. Cox proportional hazards models were used to examine the association between BMI trajectories and mortality risks. Distinct trajectory patterns were found for men and women: 'Normal Weight-Down'(N-D), 'Overweight-Normal weight' (OV-N), 'Obese I-Down' (OB I-D), and 'Obese II- Down' (OB II-D) for women; and 'Normal Weight-Down' (N-D), 'Overweight-Normal weight' (OV-N), 'Overweight-Stable' (OV-S), and 'Obese-Stable' (OB-S) for men. Comparing with OV-N, men in the OV-S group had the lowest mortality risk followed by the N-D (HR = 1.66) and OB-S (HR = 1.98) groups, after adjusting for covariates. Compared with OV-N, women in the OB II-D group with three or more chronic health conditions had higher mortality risk (HR = 1.61); however, women in OB II-D had lower risk (HR = 0.56) if they had less than three conditions. The course of BMI over time in Canadian seniors appears to follow one of four different patterns depending on gender. The findings suggest that men who were overweight at age 65 and lost weight over time had the lowest mortality risk. Interestingly, obese women with decreasing BMI have different mortality risks, depending on their chronic health conditions. The findings provide new insights concerning the associations between BMI and mortality risk.

STUDY OBJECTIVE: Despite significant declines since the late 1960s, coronary mortality remains the leading cause of death for African Americans. African Americans in the US South suffer higher rates of cardiovascular disease than African Americans in other regions; yet the mortality experiences of rural-dwelling African Americans, most of whom live in the South, have not been described in detail. This study examined urban-rural differentials in coronary mortality trends among African Americans for the period 1968-86. SETTING: The United States South, comprising 16 states and the District of Columbia. STUDY POPULATION: African American men and women aged 35-74 years. DESIGN: Analysis of urban-rural differentials in temporal trends in coronary mortality for a 19 year study period. All counties in the US South were grouped into five categories: greater metropolitan, lesser metropolitan, adjacent to metropolitan, semirural, and isolated rural. Annual age adjusted mortality rates were calculated for each urban status group. In 1968, observed excesses in coronary mortality were 29% for men and 45% for women, compared with isolated rural areas. Metropolitan areas experienced greater declines in mortality than rural areas, so by 1986 the urban-rural differentials in coronary mortality were 3% for men and 11% for women. CONCLUSIONS: Harsh living conditions in rural areas of the South precluded important coronary risk factors and contributed to lower mortality rates compared with urban areas during the 1960s. The dramatic transformation from an agriculturally based economy to manufacturing and services employment over the course of the study period contributed to improved living conditions which promoted coronary mortality declines in all areas of the South; however, the most favourable economic and mortality trends occurred in metropolitan areas.

Death on a strange isle: the mortality of the stone workers of Purbeck in the nineteenth century.

PubMed

Hinde, Andrew; Edgar, Michael

2010-01-01

This paper analyses the mortality of a group of rural workers in an extractive industry, the stone quarriers of the Isle of Purbeck in the southern English county of Dorset. The analysis uses a database created by nominal record linkage of the census enumerators' books and the Church of England baptism and burial registers to estimate age-specific death rates at all ages for males and females, and hence statistics such as the expectation of life at birth. The results are compared with mortality statistics published by the Registrar General of England and Wales (on the basis of the civil registers of deaths) for the registration district of Wareham, in which Purbeck is situated. The stone quarriers had heavier mortality levels than the rest of the population of Purbeck. Closer inspection, however, reveals that their high mortality was confined to males, and was almost entirely due to especially high mortality among boys aged less than five years. In contrast to the experience of coal and metal ore miners, adult male mortality among stone workers was no higher than that among the general population. The final section of the paper considers possible explanations for these results, and suggests that excess mortality among boys in Purbeck from lung diseases might have been responsible.

To compare mortality rates, underlying causes of death, excess mortality and years of potential life lost (YPLL) among rheumatoid arthritis (RA) patients relative to the general population. We studied an inception cohort of 87,114 Ontario RA patients and 348,456 age/sex/area-matched general population comparators over 2000 to 2013. All-cause, cause-specific, and excess mortality rates, mortality rate ratios (MRRs), and YPLL were estimated. A total of 11,778 (14% of) RA patients and 32,472 (9% of) comparators died during 508,385 and 1,769,365 person-years (PY) of follow-up, respectively, for corresponding mortality rates of 232 (95% CI 228, 236) and 184 (95% CI 182, 186) per 10,000 PYs. Leading causes of death in both groups were diseases of the circulatory system, cancer, and respiratory conditions. Increased mortality for all-cause and specific causes was observed in RA relative to the general population. MRRs were elevated for most causes of death. Age-specific mortality ratios illustrated a high excess mortality among RA patients under 45 years of age for respiratory disease and circulatory disease. RA patients lost 7,436 potential years of life per 10,000 persons, compared with 4,083 YPLL among those without RA. Mortality rates were increased in RA patients relative to the general population across most causes of death. The potential life years lost (before the age of 75) among RA patients was roughly double that among those without RA, reflecting higher rate ratios for most causes of death and RA patients dying at earlier ages.

Physical, cognitive and psychosocial functioning are frequently impaired in dialysis patients and impairment in these domains relates to poor outcome. The aim of this analysis was to compare the prevalence of impairment as measured by the Kidney Disease Quality of Life- Short Form (KDQOL-SF) subscales between the different age categories and to assess whether the association of these subscales with mortality differs between younger and older dialysis patients. This study included data from 714 prevalent hemodialysis patients, from 26 centres, who were enrolled in the CONvective TRAnsport STudy (CONTRAST NCT00205556, 09-12-2005). Baseline HRQOL domains were evaluated for patients <65 years, 65-74 years and over 75 years. Multivariable Cox proportional hazards analyses were performed to assess the relation between the separate domains and 2-year mortality. Emotional health was higher in patients over the age of 75 compared to younger patients (mean level 71, 73 and 77 for increasing age categories respectively, p = 0.02), whilst physical functioning was significantly lower in older patients (mean level 60, 48 and 40, p < 0.01). A low level of physical functioning (Hazard Ratio (HR) 1.72 [95%Confidence Interval (CI) 1.02-2.73]), emotional health (HR 1.85 [95% 1.30-2.63]), and social functioning (HR 1.59 [95% CI 1.12-2.26]), was individually associated with an increased 2-year mortality within the whole population. The absence of effect modification suggests no evidence for different relations within the older age groups. In dialysis patients, older age is associated with lower levels of physical functioning, whilst the level of emotional health is not associated with age. KDQOL-SF domains physical functioning, emotional health and social functioning are independently associated with mortality in prevalent younger and older hemodialysis patients.

Oak decline and related mortality have periodically plagued upland oak–hickory forests, particularly oak species in the red oak group, across the Ozark Highlands of Missouri, Arkansas and Oklahoma since the late 1970s. Advanced tree age and periodic drought, as well as Armillaria root fungi and oak borer attack are believed to contribute to oak decline and mortality....

To characterize the relationship between hydroxymethylglutaryl-CoA reductase inhibitors (statins) and outcomes in older persons with acute myocardial infarction (AMI). Observational study. Acute care hospitals in the United States from April 1998 to June 2001. Medicare patients aged 65 and older with a principal discharge diagnosis of AMI (N=65,020) who did and did not receive a discharge prescription for statins. The primary outcome of interest was all-cause mortality at 3 years after discharge. Of 23,013 patients with AMI assessed, 5,513 (24.0%) were receiving a statin at discharge. Nearly 40% of eligible patients (n=8,452) were aged 80 and older, of whom 1,310 (15.5%) were receiving a statin at discharge. In a multivariable model taking into account demographic, clinical, physician and hospital characteristics, and propensity score, discharge statin therapy was associated with significantly lower 3-year mortality (hazard ratio (HR)=0.89 (95% confidence interval (CI)=0.83-0.96)). In an analysis stratified by age, discharge statins were associated with lower mortality in patients younger than 80 (HR=0.84, 95% CI=0.76-0.92) but not in those aged 80 and older (HR=0.97, 95% CI=0.87-1.09). Statin therapy is associated with lower mortality in older patients with AMI younger than 80 but not in those aged 80 and older, as a group. This finding questions whether statin efficacy data in younger patients can be broadly applied to the very old and indicates the need for further study of this group.

Background Coronary heart disease (CHD) mortality in England fell by approximately 6% every year between 2000 and 2007. However, rates fell differentially between social groups with inequalities actually widening. We sought to describe the extent to which this reduction in CHD mortality was attributable to changes in either levels of risk factors or treatment uptake, both across and within socioeconomic groups. Methods and Findings A widely used and replicated epidemiological model was used to synthesise estimates stratified by age, gender, and area deprivation quintiles for the English population aged 25 and older between 2000 and 2007. Mortality rates fell, with approximately 38,000 fewer CHD deaths in 2007. The model explained about 86% (95% uncertainty interval: 65%–107%) of this mortality fall. Decreases in major cardiovascular risk factors contributed approximately 34% (21%–47%) to the overall decline in CHD mortality: ranging from about 44% (31%–61%) in the most deprived to 29% (16%–42%) in the most affluent quintile. The biggest contribution came from a substantial fall in systolic blood pressure in the population not on hypertension medication (29%; 18%–40%); more so in deprived (37%) than in affluent (25%) areas. Other risk factor contributions were relatively modest across all social groups: total cholesterol (6%), smoking (3%), and physical activity (2%). Furthermore, these benefits were partly negated by mortality increases attributable to rises in body mass index and diabetes (−9%; −17% to −3%), particularly in more deprived quintiles. Treatments accounted for approximately 52% (40%–70%) of the mortality decline, equitably distributed across all social groups. Lipid reduction (14%), chronic angina treatment (13%), and secondary prevention (11%) made the largest medical contributions. Conclusions The model suggests that approximately half the recent CHD mortality fall in England was attributable to improved treatment uptake. This benefit occurred evenly across all social groups. However, opposing trends in major risk factors meant that their net contribution amounted to just over a third of the CHD deaths averted; these also varied substantially by socioeconomic group. Powerful and equitable evidence-based population-wide policy interventions exist; these should now be urgently implemented to effectively tackle persistent inequalities.

To analyze the gender difference of life expectancy in urban people of China and to explore both age-specific and cause-specific contributions to the changing differences in life expectancy on genders. Data on life expectancy (male and female) and mortality were obtained from the"Annual Statistics of public health in China". Male-female gender difference was analyzed by decomposition methodologies, including age-specific decomposition and the cause-specific decomposition. Women had lived much longer than men in the Chinese urban citizens, with remarkable gains in life expectancy since 2005. Difference in gender reached a peak in 2007, with the gap of 5.3 years. Differences on mortality between men and women in the 60-79 age groups made the largest contribution (42%-47%) to the gap of 6 years on life expectancy in genders. With the widening of the gaps in gender on life expectancy between 2005 and 2007, faster declining of mortality among groups of women in age 0-1 age and over 75 years old groups made the largest contributions. Between 2007 and 2008, along with the reduction of gaps in gender, all the age groups except the 1-15 and 50-55 year-olds showed negative efforts. In 2009-2010, the widening gaps in gender on life expectancy were caused by the positive effect in the 60-70 age group. Among all the causes of death, cancer (1.638-2.019 years), circulatory diseases (1.271-1.606 years), respiratory diseases (0.551-0.800 years) made the largest contributions to the gender gap. 33%-38% of the gaps in gender were caused by cancer and among all the cancers, among which lung cancer contributed 0.6 years to the overall gap. Contribution of cancers to the gender gap was reducing, but when time went on it was mostly influenced by the narrowing effect caused by liver cancer on the gap in gender. Traffic accidents and suicidal issues were the external causes that influencing the gender gap and contributing 10.60%-15.78% to the overall differentials. Public health efforts in reducing the excess mortalities for cancer, circulatory and respiratory diseases, suicide, among men in particular, will further narrow the gender gap on life expectancy in the urban cities of China.

In England, the impact of increased use of antidepressant medications is unclear. We examine associations between antidepressant use, suicide and antidepressant poisoning mortality, adjusted for important covariates. Data on suicide and antidepressant poisoning mortality were provided by the Office for National Statistics. Prescription data were provided by the Department of Health. Age- and sex-specific prescribing rates were estimated from The Health Improvement Network primary care data. We measured the association between prescribing, suicide and poisoning mortality after adjusting for age, sex, calendar year, prescribing rates and use of newer antidepressants drugs. The prevalence of antidepressant treatment increased during the 1990s for all age and sex groups. Treatment prevalence remained constant from 2002 but declined among children and adolescents. Between 1993 and 2004, age-standardized rates for suicide decreased from 98.2 to 81.3 per million populations and for antidepressants from 9.2 to 7.4 per million populations. Before adjustment, increased antidepressant prescribing was associated with a decrease in suicide (r(s) = -0.90, P < 0.001) and antidepressant poisoning mortality rates (r(s) = -0.65, P = 0.023). This association disappeared after adjustment. In England, at a population level, there does not appear to be an association between antidepressant prescribing and antidepressant poisoning mortality or suicide.

Tendency for mortality in hypertension has not been well-characterized in European Union (EU). Mortality data from 1980 to 2011 in EU were used to calculate age-standardized mortality rate (ASMR, per 100,000), annual percentage change (APC) and average annual percentage change (AAPC). The Joinpoint Regression Program was used to compare the changes in tendency. Mortality rates in the most recent year studied vary between different countries, with the highest rates observed in Slovakia men and Estonia women. A downward trend in ASMR was demonstrated over all age groups. Robust decreases in ASMR were observed for both men (1991-1994, APC = -13.54) and women (1996-1999, APC = -14.80) aged 55-65 years. The tendency of systolic blood pressure (SBP) from 1980 to 2009 was consistent with ASMR, and the largest decrease was observed among Belgium men and France women. In conclusion, SBP associated ASMR decreased significantly on an annual basis from 1980 to 2009 while a slight increase was observed after 2009. Discrepancies in ASMR from one country to another in EU are significant during last three decades. With a better understanding of the tendency of the prevalence of hypertension and its mortality, efforts will be made to improve awareness and help strict control of hypertension.

To analyze trends in mortality in Argentina, Chile, Colombia and Mexico, between 2000 and 2011, by sex and 5-year age groups (between 20 and 79 years of age). Mortality vital statistics and census data or projected population estimates were used for each country. Age-specific mortality rates and the years of life lost were calculated. Among the countries analyzed, Mexico had the highest mortality rate and lost the most years of life due to diabetes. Between 2000 and 2011, Mexicans lost an average of 1.13 years of life, while Colombia (0.24), Argentina (0.21) and Chile (0.18) lost considerably fewer life years. In general, deaths from diabetes were higher in men than in women except in Colombia. Nearly 80% of years of life lost due to diabetes occurred between 50 and 74 years of age in the four countries. Diabetes is a huge challenge for Latin America, especially in Mexico where mortality due to diabetes is accelerating. Even though the proportion of deaths due to diabetes in Argentina, Chile and Colombia is smaller, this disease figures among the main causes of death in these countries. Copyright © 2014 SESPAS.

Objective: Peptic ulcer perforation continues to be a major surgical problem. In this study, risk factors that influence morbidity and mortality in perforated peptic ulcer disease were examined. Material and Methods: Files of 148 patients who were included in the study due to peptic ulcer perforation between January 2006 and December 2010 were retrospectively analyzed. Data regarding age, gender, complaints, time elapsed between onset of symptoms and hospital admission, physical examination findings, co-morbid diseases, laboratory and imaging findings, length of hospital stay, morbidity and mortality were recorded. Results: The study group included 129 (87.2%) male and 19 (12.8%) female patients. The mean age was 51.7±20 (15-88) years. Forty five patients (30.4%) had at least one co-morbid disease. In the postoperative period, 30 patients (20.3%) had complications. The most common complication was wound infection. Mortality was observed in 27 patients (18.2%). The most common cause of mortality was sepsis. Multivariate analysis revealed age over 60 years, presence of co-morbidities and Mannheim peritonitis index as independent risk factors for morbidity. Age over 60 years, time to admission and Mannheim peritonitis index were detected as independent risk factors for mortality. Conclusion: Early diagnosis and proper treatment are important in patients presenting with peptic ulcer perforation. PMID:25931940

Extreme heat has been associated with increased mortality, particularly in temperate climates. Few epidemiologic studies have considered the Pacific Northwest region in their analyses. This study quantified the historical (May to September, 1980-2010) heat-mortality relationship in the most populous Pacific Northwest County, King County, Washington. A relative risk (RR) analysis was used to explore the relationship between heat and all-cause mortality on 99th percentile heat days, while a time series analysis, using a piece-wise linear model fit, was used to estimate the effect of heat intensity on mortality, adjusted for temporal trends. For all ages, all causes, we found a 10 % (1.10 (95 % confidence interval (CI), 1.06, 1.14)) increase in the risk of death on a heat day versus non-heat day. When considering the intensity effect of heat on all-cause mortality, we found a 1.69 % (95 % CI, 0.69, 2.70) increase in the risk of death per unit of humidex above 36.0 °C. Mortality stratified by cause and age produced statistically significant results using both types of analyses for: all-cause, non-traumatic, circulatory, cardiovascular, cerebrovascular, and diabetes causes of death. All-cause mortality was statistically significantly modified by the type of synoptic weather type. These results demonstrate that heat, expressed as humidex, is associated with increased mortality on heat days, and that risk increases with heat's intensity. While age was the only individual-level characteristic found to modify mortality risks, statistically significant increases in diabetes-related mortality for the 45-64 age group suggests that underlying health status may contribute to these risks.

The associations of parity and maternal age with small-for-gestational-age, preterm, and neonatal and infant mortality: a meta-analysis

PubMed Central

2013-01-01

Background Previous studies have reported on adverse neonatal outcomes associated with parity and maternal age. Many of these studies have relied on cross-sectional data, from which drawing causal inference is complex. We explore the associations between parity/maternal age and adverse neonatal outcomes using data from cohort studies conducted in low- and middle-income countries (LMIC). Methods Data from 14 cohort studies were included. Parity (nulliparous, parity 1-2, parity ≥3) and maternal age (<18 years, 18-<35 years, ≥35 years) categories were matched with each other to create exposure categories, with those who are parity 1-2 and age 18-<35 years as the reference. Outcomes included small-for-gestational-age (SGA), preterm, neonatal and infant mortality. Adjusted odds ratios (aOR) were calculated per study and meta-analyzed. Results Nulliparous, age <18 year women, compared with women who were parity 1-2 and age 18-<35 years had the highest odds of SGA (pooled adjusted OR: 1.80), preterm (pooled aOR: 1.52), neonatal mortality (pooled aOR: 2.07), and infant mortality (pooled aOR: 1.49). Increased odds were also noted for SGA and neonatal mortality for nulliparous/age 18-<35 years, preterm, neonatal, and infant mortality for parity ≥3/age 18-<35 years, and preterm and neonatal mortality for parity ≥3/≥35 years. Conclusions Nulliparous women <18 years of age have the highest odds of adverse neonatal outcomes. Family planning has traditionally been the least successful in addressing young age as a risk factor; a renewed focus must be placed on finding effective interventions that delay age at first birth. Higher odds of adverse outcomes are also seen among parity ≥3 / age ≥35 mothers, suggesting that reproductive health interventions need to address the entirety of a woman’s reproductive period.

Objective Although obesity is recognized as an important risk of mortality, how the amount and distribution of body fat affect mortality risk is unclear. Furthermore, whether fat distribution confers any additional risk of mortality in addition to fat amount is not understood. Methods This data linkage cohort study included 16415 participants (8554 females) aged 18 to 89 years from National Health and Nutrition Examination Survey III (1988–1994) and its linked mortality data (31 December 2011). Cox proportional hazard models and parametric survival models were used to estimate the association between body fat percentage (BF%), based on bioelectrical impedance analysis, and waist-hip ratio (WHR) with mortality. Results A total of 4999 deaths occurred during 19-year follow-up. A U-shaped association between BF% and mortality was found in both sexes, with the adjusted hazard ratios for other groups between 1.02 (95% confidence interval: 0.89, 1.18) and 2.10 (1.47, 3.01) when BF% groups of 25–30% in males and 30–35% in females were used as references. A non-linear relationship between WHR and mortality was detected in males, with the adjusted hazard ratios among other groups ranging from 1.05 (0.94, 1.18) to 1.52 (1.15, 2.00) compared with the WHR category of 0.95–1.0. However in females, the death risk constantly increased across the WHR spectrum. Joint impact of BF% and WHR suggested males with BF% of 25–30% and WHR of 0.95–1.0 and females with BF% of 30–35% and WHR <0.9 were associated with the lowest mortality risk and longest survival age compared with their counterparts in other categories. Conclusions This study supported the use of body fat distribution in addition to fat amount in assessing the risk of all-cause mortality. PMID:29474498

Synoptic circulation patterns (large-scale weather systems) affect ambient levels of air pollution, as well as the relationship between air pollution and human health. To investigate the air pollution-mortality relationship within weather types and seasons, and to determine which combination of atmospheric conditions may pose increased health threats in the elderly age categories. The relative risk of mortality (RR) due to air pollution was examined using Poisson generalized linear models (GLMs) within specific weather types. Analysis was completed by weather type and age group (all ages, ≤64, 65-74, 75-84, ≥85 years) in ten Canadian cities from 1981 to 1999. There was significant modification of RR by weather type and age. When examining the entire population, weather type was shown to have the greatest modifying effect on the risk of dying due to ozone (O3). This effect was highest on average for the dry tropical (DT) weather type, with the all-age RR of mortality at a population weighted mean (PWM) found to be 1.055 (95% CI 1.026-1.085). All-weather type risk estimates increased with age due to exposure to carbon monoxide (CO), nitrogen dioxide (NO2), and sulphur dioxide (SO2). On average, RR increased by 2.6, 3.8 and 1.5% for the respective pollutants between the ≤64 and ≥85 age categories. Conversely, mean ozone estimates remained relatively consistent with age. Elevated levels of air pollution were found to be detrimental to the health of elderly individuals for all weather types. However, the entire population was negatively effected by air pollution on the hot dry (DT) and hot humid (MT) days. We identified a significant modification of RR for mortality due to air pollution by age, which is enhanced under specific weather types. Efforts should be targeted at minimizing pollutant exposure to the elderly and/or all age groups with respect to weather type in question. Crown Copyright © 2013 Published by Elsevier Inc.

Climate change is predicted to increase the frequency and duration of extreme-heat events and associated health outcomes. This study used data from the historical heat-health outcome relationship, and a unique prediction model, to estimate mortality for 2025 and 2045. For each one degree change in humidex above threshold, we find a corresponding 1.83% increase in mortality for all ages, all non-traumatic causes of death in King County, Washington. Mortality is projected to increase significantly in 2025 and 2045 for the 85 and older age group (2.3-8.0 and 4.0-22.3 times higher than baseline, respectively).

Aging is associated with increased inflammation following sepsis. The purpose of this study was to determine whether this represents a fundamental age-based difference in the host response or is secondary to the increased mortality seen in aged hosts. Prospective, randomized controlled study. Animal laboratory in a university medical center. Young (6-12 weeks) and aged (20-24 months) FVB/N mice. Mice were subjected to 2 x 25 or 1 x 30 cecal ligation and puncture (CLP). Survival was similar in young mice subjected to 2 x 25 CLP and aged mice subjected to 1 x 30 CLP (p = 0.15). Young mice subjected to 1 x 30 CLP had improved survival compared with the other groups (p < 0.05). When injury was held constant but mortality was greater, both systemic and peritoneal levels of tumor necrosis factor-alpha, interleukin (IL)-6, IL-10, and monocyte chemotactic protein-1 were elevated 24 hours after CLP in aged animals compared with young animals (p < 0.05). When mortality was similar but injury severity was different, there were no significant differences in systemic cytokines between aged mice and young mice. In contrast, peritoneal levels of tumor necrosis factor-alpha, IL-6, and IL-10 were higher in aged mice subjected to 1 x 30 CLP than young mice subjected to 2 x 25 CLP despite their similar mortalities (p < 0.05). There were no significant differences in either bacteremia or peritoneal cultures when animals of different ages sustained similar injuries or had different injuries with similar mortalities. Aged mice are more likely to die of sepsis than young mice when subjected to an equivalent insult, and this is associated with increases in both systemic and local inflammation. There is an exaggerated local but not systemic inflammatory response in aged mice compared with young mice when mortality is similar. This suggests that systemic processes that culminate in death may be age independent, but the local inflammatory response may be greater with aging.

Hispanics are the most rapidly growing minority group in the United States, and Mexican Americans, Puerto Ricans and Cuban Americans are the three largest Hispanic subgroups. Among Hispanics, type 2 diabetes is the fifth leading cause of death. This paper examines diabetes-related mortality in Mexican Americans, Puerto Ricans, and Cuban Americans over 35 years of age in the United States during 1996 and 1997. Using data from the National Vital Statistics System and the 1990 and 2000 censuses, we calculated age-adjusted and age-specific diabetes-related death rates for Mexican Americans, Puerto Ricans, and Cuban Americans over 35 years of age. Diabetes-related deaths were determined to be any death for which diabetes was coded as either the underlying or contributing cause of death. The diabetes-related mortality rate for Mexican Americans (251 per 100,000) and Puerto Ricans (204 deaths per 100,000) was twice as high as the diabetes-related mortality rate for Cuban Americans (101 deaths per 100,000). Cuban American decedents had the highest proportion of deaths with diabetes coded as the underlying cause of death (44%). After diabetes, heart disease (31%) followed by cancer (8%) and stroke (6%) were the most frequent primary underlying causes of diabetes-related deaths in all three ethnic groups. Our analyses of these data demonstrate that diabetes-related mortality differed among Mexican Americans, Puerto Ricans and Cuban Americans more than 35 years of age in the United States in 1996 and 1997. Socioeconomic factors such as low educational attainment and low income may be factors that contributed to the disparities in these mortality rates for different subgroups. Further research is needed to update these findings and to investigate explanatory risk factors. Diversity among Hispanic subgroups has persisted in recent years and should be considered when health policies and services targeted at these populations are developed.

To evaluate whether late-career unemployment is associated with increased all-cause mortality, functional disability, and depression among older adults in Taiwan. In this long-term prospective cohort study, data were retrieved from the Taiwan Longitudinal Study on Aging. This study was conducted from 1996 to 2007. The complete data from 716 men and 327 women aged 50-64 years were retrieved. Participants were categorized as normally employed or unemployed depending on their employment status in 1996. The cumulative number of unemployment after age 50 was also calculated. Logistic regression analysis was used to examine the effect of the association between late-career unemployment and cumulative number of late-career unemployment on all-cause mortality, functional disability, and depression in 2007. The average age of the participants in 1996 was 56.3 years [interquartile range (IQR)=7.0]. A total of 871 participants were in the normally employed group, and 172 participants were in the unemployed group. After adjustment of gender, age, level of education, income, self-rated health and major comorbidities, late-career unemployment was associated with increased all-cause mortality [Odds ratio (OR)=2.79; 95% confidence interval (CI)=1.74-4.47] and functional disability [OR=2.33; 95% CI=1.54-3.55]. The cumulative number of late-career unemployment was also associated with increased all-cause mortality [OR=1.91; 95% CI=1.35-2.70] and functional disability [OR=2.35; 95% CI=1.55-3.55]. Late-career unemployment and cumulative number of late-career unemployment are associated with increased all-cause mortality and functional disability. Older adults should be encouraged to maintain normal employment during the later stage of their career before retirement. Employers should routinely examine the fitness for work of older employees to prevent future unemployment. Copyright © 2016. Published by Elsevier Ireland Ltd.

Excess mortality in severe mental illness (defined here as schizophrenia, schizoaffective disorders, and bipolar affective disorders) is well described, but little is known about this inequality in ethnic minorities. We aimed to estimate excess mortality for people with severe mental illness for five ethnic groups (white British, black Caribbean, black African, south Asian, and Irish) and to assess the association of ethnicity with mortality risk. We conducted a longitudinal cohort study of individuals with a valid diagnosis of severe mental illness between Jan 1, 2007, and Dec 31, 2014, from the case registry of the South London and Maudsley Trust (London, UK). We linked mortality data from the UK Office for National Statistics for the general population in England and Wales to our cohort, and determined all-cause and cause-specific mortality by ethnicity, standardised by age and sex to this population in 2011. We used Cox proportional hazards regression to estimate hazard ratios and a modified Cox regression, taking into account competing risks to derive sub-hazard ratios, for the association of ethnicity with all-cause and cause-specific mortality. We identified 18 201 individuals with a valid diagnosis of severe mental illness (median follow-up 6·36 years, IQR 3·26-9·92), of whom 1767 died. Compared with the general population, age-and-sex-standardised mortality ratios (SMRs) in people with severe mental illness were increased for a range of causes, including suicides (7·65, 95% CI 6·43-9·04), non-suicide unnatural causes (4·01, 3·34-4·78), respiratory disease (3·38, 3·04-3·74), cardiovascular disease (2·65, 2·45-2·86), and cancers (1·45, 1·32-1·60). SMRs were broadly similar in different ethnic groups with severe mental illness, although the south Asian group had a reduced SMR for cancer mortality (0·49, 0·21-0·96). Within the cohort with severe mental illness, hazard ratios for all-cause mortality and sub-hazard ratios for natural-cause and unnatural-cause mortality were lower in most ethnic minority groups relative to the white British group. People with severe mental illness have excess mortality relative to the general population irrespective of ethnicity. Among those with severe mental illness, some ethnic minorities have lower mortality than the white British group, for which the reasons deserve further investigation.

To compare the outcomes of umbilical hernia repair in patients with and without signs of portal hypertension, such as esophageal varices or ascites; to assess the effect of emergency surgery on complication rates; and to identify predictors of postoperative mortality. Database search from January 1, 2005, through December 31, 2009. North American hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program initiative. We studied patients who underwent umbilical hernia repair. Those with congestive heart failure, disseminated malignant tumor, or chronic renal failure while undergoing dialysis were excluded. Preoperative variables and perioperative course were analyzed. Main outcome measures were morbidity and mortality after umbilical hernia repair. A total of 390 patients with ascites and/or esophageal varices formed the study group, and the remaining 22 952 patients formed the control group. The overall morbidity and mortality rates for the study group were 13.1% and 5.1%, whereas these rates were 3.9% and 0.1% for the control group, respectively (P < .001). For the study group, the mortality after elective repair among patients with a model for end-stage liver disease (MELD) score greater than 15 was 11.1% compared with 1.3% in patients with a MELD score of 15 or less. The patients with ascites and/or esophageal varices underwent emergency surgery more frequently than the control group (37.7% vs 4.9%; P < .001). Emergency surgery for the study group was associated with a higher morbidity than elective surgery (20.8% vs 8.3%; P < .001) but not a significantly higher mortality (7.4% vs 3.7%; P = .11). However, logistic regression analysis showed that age older than 65 years, MELD score higher than 15, albumin level less than 3.0 g/dL (to convert to grams per liter, multiply by 10), and sepsis at presentation were more predictive of postoperative mortality. Umbilical hernia repair in the presence of ascites and/or esophageal varices is associated with significant postoperative complication rates. Emergency surgery is associated with higher morbidity rates but not significantly higher mortality rates. Elective repair of umbilical hernia should be avoided for those with adverse predictors, such as age older than 65 years, MELD score higher than 15, and albumin level less than 3.0 g/dL.

Colorectal cancer (CRC) is the third leading cause of mortality due to cancer (with over 50,000 deaths annually), representing 9% of all cancer deaths in the United States (1). In particular, the African-American CRC mortality rate is among the highest reported for any race/ethnic group. Meanwhile, the CRC mortality rate for Hispanics is 15-19% lower than that for non-Hispanic Caucasians (2). While factors such as obesity, age, and socio-economic status are known to associate with CRC mortality, do these and other potential factors correlate with CRC death in the same way across races? This research linked CRC mortality data obtained from the National Cancer Institute with data from the United States Census Bureau, the Centers for Disease Control and Prevention, and the National Solar Radiation Database to examine geographic and racial/ethnic differences, and develop a spatial regression model that adjusted for several factors that may attribute to health disparities among ethnic/racial groups. This analysis showed that sunlight, obesity, and socio-economic status were significant predictors of CRC mortality. The study is significant because it not only verifies known factors associated with the risk of CRC death but, more importantly, demonstrates how these factors vary within different racial groups. Accordingly, education on reducing risk factors for CRC should be directed at specific racial groups above and beyond creating a generalized education plan.

Necrotizing fasciitis (NF) is a rapidly progressive disease that requires urgent surgical debridement for survival. Interhospital transfer (IT) may be associated with delay to operation, which could increase mortality. We hypothesized that mortality would be higher in patients undergoing surgical debridement for necrotizing fasciitis after IT compared to Emergency Department (ED) admission. We performed a retrospective cohort analysis from 2000-2006 using the Nationwide Inpatient Sample. Inclusion criteria were age >18 years, primary diagnosis of NF, and surgical therapy within 72 hours of admission. Logistic regression was used to assess the relationship between admission source, patient and hospital variables, and mortality. We identified 9,958 cases over the study period. Patients in the ED group were more likely to be nonwhite and of lower income when compared with patients in the IT group. Unadjusted mortality was higher in the IT group than ED group (15.5% vs 8.7%, P < .001). After adjusting for potential confounders, odds of mortality were still greater in the IT (OR 2.04, CI 95% 1.60-2.59, P < .001). Interhospital transfer is associated with increased risk of in-hospital mortality after surgical therapy for NF, a finding which persists after controlling for patient and hospital level variables.

In the United States, the association between income inequality and mortality has been fairly consistent. However, few studies have explicitly examined the impact of race. Studies that have either stratified outcomes by race or conducted analyses within race-specific groups suggest that the income inequality/mortality relation may differ for blacks and whites. The factors explaining the association may also differ for the two groups. Multivariate ordinary least squares regression analysis was used to examine associations between study variables. We used three measures of income inequality to examine the association between income inequality and age-adjusted all-cause mortality among blacks and whites separately. We also examined the role of racial residential segregation and concentrated poverty in explaining associations among groups. Metropolitan areas were included if they had a population of at least 100,000 and were at least 10 percent black. There was a positive income inequality/mortality association among blacks and an inverse association among whites. Racial residential segregation completely attenuated the income inequality/mortality relationship for blacks, but was not significant among whites. Concentrated poverty was a significant predictor of mortality rates in both groups but did not confound associations. The implications of these findings and directions for future research are discussed.

This study investigated age-related differences in surgically treated patients with gastric cancer, and aimed to identify factors associated with outcome. Data from the Dutch Upper Gastrointestinal Cancer Audit were used. All patients with non-cardia gastric cancer registered between 2011 and 2015 who underwent surgery were selected. Patients were analysed by age group (less than 70 years versus 70 years or more). Multivariable logistic regression was used to assess the influence of clinicopathological factors on morbidity and mortality. A total of 1109 patients younger than 70 years and 1206 aged 70 years or more were included. Patients aged at least 70 years had more perioperative or postoperative complications (41·2 versus 32·5 per cent; P < 0·001) and a higher 30-day mortality rate (7·9 versus 3·2 per cent; P < 0·001) than those younger than 70 years. In multivariable analysis, age 70 years or more was associated with a higher risk of complications (odds ratio 1·29, 95 per cent c.i. 1·05 to 1·59). Postoperative mortality was not significantly associated with age. In the entire cohort, morbidity and mortality were influenced most by ASA grade, neoadjuvant chemotherapy and type of resection. ASA grade, neoadjuvant chemotherapy and type of resection are independent predictors of morbidity and death in patients with gastric cancer, irrespective of age. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

To assess the prevalence of metabolic syndrome (MS) and its association with mortality of cerebro-cardiovascular diseases in senile population. Data were collected from 1926 people aged 60 and over, who took part in routine health examination in our hospital from 1996 to 1997. All subjects were followed up for 10 years. MS was diagnosed by using the definition recommended by Chinese Diabetic Society in 2004. Cox-proportional hazards models were used in survival analyses and to calculate the relative risk (RR) of cerebro-cardiovascular diseases mortality. The prevalence of MS was 25.03% (n = 482, Group 2) in this population. The 10 year mortality of cerebro-cardiovascular diseases was significantly higher (6.82/1000-person year vs. 2.55/1000-person year, P < 0.05) and the cumulative survival rate was significantly lower (92.46%vs. 97.14%, P < 0.05) in group 2 compared that in group 1 (non-MS, n = 1444). Compared with group 1, RR of cerebro-cardiovascular diseases mortality was 2.52 (95% CI 1.367 - 4.661, P < 0.05) in group 2. There was a high prevalence of MS in the senile population and MS was associated with higher 10 years mortality of cerebro-cardiovascular diseases.

Abnormal hemoglobin levels are a risk factor for Alzheimer's disease (AD). Although the mechanism underlying these associations is elusive, inadequate micronutrients, particularly folate and vitamin B12, may increase the risk for anemia, cognitive impairment, and AD. In this study, we investigated whether the nutritional status of folate and vitamin B12 is involved in the association between low hemoglobin levels and the risk of AD mortality. Data were obtained from the 1999-2006 National Health and Nutrition Examination Survey (NHANES) and the NHANES (1999-2006) Linked Mortality File. A total of 4,688 participants aged ≥60 years with available baseline data were included in this study. We categorized three groups based on the quartiles of folate and vitamin B12 as follows: Group I (low folate and vitamin B12); Group II (high folate and low vitamin B12 or low folate and high vitamin B12); and Group III (high folate and vitamin B12). Of 4,688 participants, 49 subjects died due to AD. After adjusting for age, sex, ethnicity, education, smoking history, body mass index, the presence of diabetes or hypertension, and dietary intake of iron, significant increases in the AD mortality were observed in Quartile1 for hemoglobin (HR: 8.4, 95% CI: 1.4-50.8), and the overall risk of AD mortality was significantly reduced with increases in the quartile of hemoglobin (p for trend = 0.0200), in subjects with low levels of both folate and vitamin B12 at baseline. This association did not exist in subjects with at least one high level of folate and vitamin B12. Our finding shows the relationship between folate and vitamin B12 levels with respect to the association between hemoglobin levels and AD mortality.

This study was undertaken to evaluate trends in heat failure hospitalizations (HFHs) and 1-year mortality of HFH in Lombardy, the largest Italian region, from 2000 to 2012. Hospital discharge forms with HF-related ICD-9 CM codes collected from 2000 to 2012 by the regional healthcare service (n=699797 in 370538 adult patients), were analyzed with respect to in-hospital and 1-year mortality; Group (G) 1 included most acute HF episodes with primary cardiac diagnosis (70%); G2 included cardiomyopathies without acute HF codes (17%); and G3 included non-cardiac conditions with HF as secondary diagnosis (13%). Patients experiencing their first HFH since 2005 were analyzed as incident cases (n=216782). Annual HFHs number (mean 53830) and in-hospital mortality (9.4%) did not change over the years, the latter being associated with increasing age (p<0.0001) and diagnosis Group (G1 9.1%, G2 5.6%, G3 15.9%, p<0.0001). Incidence of new cases decreased over the years (3.62 [CI 3.58-3.67] in 2005 to 3.13 [CI 3.09-3.17] in 2012, per 1000 adult inhabitants/year, p<0.0001), with an increasing proportion of patients aged ≥85y (22.3% to 31.4%, p<0.0001). Mortality lowered over time in <75y incident cases, both in-hospital (5.15% to 4.36%, p<0.0001) and at 1-year (14.8% to 12.9%, p=0.0006). The overall burden and mortality of HFH appear stable for more than a decade. However, from 2005 to 2012, there was a reduction of new, incident cases, with increasing age at first hospitalization. Meanwhile, both in-hospital and 1-year mortality decreased in patients aged <75y, possibly due to improved prevention and treatment. Copyright © 2017 Elsevier B.V. All rights reserved.

The impact of fiscal austerity on suicide mortality: Evidence across the 'Eurozone periphery'.

2015-11-01

While linkages between some macroeconomic phenomena and suicides in some countries have been explored, only two studies, hitherto, have established a causal relationship between fiscal austerity and suicide, albeit in a single country. The aim of this study is to provide the first systematic multiple-country evidence of a causal relationship of fiscal austerity on time-, gender-, and age-specific suicide mortality across five Eurozone peripheral countries, namely Greece, Ireland, Italy, Portugal and Spain over the period 1968-2012, while controlling for various socioeconomic differences. The impact of fiscal adjustments is found to be gender-, age- and time-specific. Specifically, fiscal austerity has short-, medium- and long-run suicide increasing effects on the male population in the 65-89 age group. A 1% reduction in government spending is associated with a 1.38%, 2.42% and 3.32% increase in the short-, medium- and long-run, respectively, of male suicides rates in the 65-89 age group in the Eurozone periphery. These results are highly robust to alternative measures of fiscal austerity. Improved labour market institutions help mitigate the negative effects of fiscal austerity on suicide mortality.

Elderly persons with acute poisoning in the emergency department (ED) and prognostic factors of outcomes have not been well addressed in previous research. This study aimed to investigate the characteristics of elderly patients with acute poisoning visiting the ED, and to identify the possible predictive factors of mortality. Patients aged > or = 65 years with acute poisoning who visited the ED in Taipei Veterans General Hospital from January 1, 2006 through to September 30, 2008 were enrolled in the study. We collected demographic information on underlying diseases, initial presentations, causes and toxic substances, complications, dispositions, and outcomes. Analyses were conducted among different groups categorized according to age, suicide attempt, and outcome. Multiple logistic regression was applied to identify possible predictive clinical factors influencing mortality in the elderly with acute poisoning. A total of 250 patients were enrolled in the study, with a mean age of 77 years and male predominance. The most common cause of intoxication was unintentional poisoning. Medication accounted for 57.6% of poisonous substances, of which benzodiazepine was the most common drug, followed by warfarin. The overall mortality rate was 9.6%. The average length of stay in the ED increased significantly in the old (65-74 years), very old (75-84 years) and extremely old (> or = 85 years) groups. Suicide attempt patients experienced more complications including respiratory failure, aspiration pneumonia, hypotension and mortality. Three clinical predictive factors of mortality were identified: herbicide poisoning, hypotension and respiratory failure upon presentation. Our results demonstrated that elderly patients with acute poisoning had a mortality rate of 9.6%. Suicide attempts resulted in more serious complications. The risk factors for mortality were herbicide intoxication, hypotension and respiratory failure. Copyright 2010 Elsevier. Published by Elsevier B.V. All rights reserved.

The historical Japanese influenza vaccination program targeted at schoolchildren provides a unique opportunity to evaluate the indirect benefits of vaccinating high-transmitter groups to mitigate disease burden among seniors. Here we characterize the indirect mortality benefits of vaccinating schoolchildren based on data from Japan and the US. We compared age-specific influenza-related excess mortality rates in Japanese seniors aged ≥65 years during the schoolchildren vaccination program (1978-1994) and after the program was discontinued (1995-2006). Indirect vaccine benefits were adjusted for demographic changes, socioeconomics and dominant influenza subtype; US mortality data were used as a control. We estimate that the schoolchildren vaccination program conferred a 36% adjusted mortality reduction among Japanese seniors (95%CI: 17-51%), corresponding to ∼1,000 senior deaths averted by vaccination annually (95%CI: 400-1,800). In contrast, influenza-related mortality did not change among US seniors, despite increasing vaccine coverage in this population. The Japanese schoolchildren vaccination program was associated with substantial indirect mortality benefits in seniors.

The association between obesity and all-cause mortality is controversial and may differ according to subjects' characteristics. Blood pressure variability (BPV) may be increased in obese individuals and thus impair prognosis. The purpose of this study was to evaluate whether the relationship between obesity and mortality is influenced by short-term ambulatory BPV. The analysis was performed in 8724 participants (54% men) aged 51 ± 15 years enrolled in 8 prospective studies in Australia, Italy, Japan, and U.S.A. The predictive power of obesity (BMI >=30 kg/m2) for mortality was evaluated from multivariable Cox models in the subjects stratified by high or low nocturnal BPV (above or below the median). Obese participants (N = 1286) had higher age-and-sex adjusted systolic and diastolic BPV than the non-obese participants (p = 0.002/<0.001). Obese subjects with high systolic or diastolic BPV had higher nocturnal heart rate (p = 0.01/<0.001) than obese subjects with low BPV and were more frequently diabetic (p<0.001) and heavy alcohol drinkers (p < 0.001). During a median follow-up of 6.4 years there were 361 deaths, 4.7% in the obese and 4.0% in the non-obese individuals (P = NS). However, the risk of mortality among the obese subjects greatly differed according to BPV level. In Cox models including age, sex, mean ambulatory BP, smoking, alcohol use, diabetes, cholesterol, creatinine, and nocturnal heart rate, the obese group with high systolic BPV had a doubled risk of mortality compared to the non-obese group (HR,2.0, 95%CI,1.4-2.9, p < 0.001), whereas the risk was not increased in the obese group with low BPV (P = 0.81). Similar results were found for diastolic BPV, with a HR of 1.7 (1.2-2.5, p = 0.002) in the high BPV group and no association at all with mortality (p = 0.87) in the low BPV group. Inclusion of night-time BP dipping in the regressions did not change the strength of the associations. These data show that high nocturnal BPV greatly increases the risk of mortality related to obesity. High BPV is accompanied by increased heart rate and may reflect the influence of transient BP elevations related to sleep apnea and/or baroreflex dysfunction.

Background : This study aimed to profile the epidemiology of injury among preschool-aged and school-aged children in comparison to those in adults. Methods : According to the Trauma Registry System of a level I trauma center, the medical data were retrieved from 938 preschool-aged children (aged less than seven years), 670 school-aged children (aged 7⁻12 years), and 16,800 adults (aged 20⁻64 years) between 1 January 2009 and 31 December 2016. Two-sided Pearson’s, chi-squared, and Fisher’s exact tests were used to compare categorical data. A one-way analysis of variance (ANOVA) with the Games-Howell post-hoc test was used to assess the differences in continuous variables among different groups of patients. The mortality outcomes of different subgroups were assessed by a multivariable regression model under the adjustment of sex, injury mechanisms, and injury severity. Results : InFsupppjury mechanisms in preschool-aged and school-aged children were remarkably different from that in adults; in preschool-aged children, burns were the most common cause of injury requiring hospitalization (37.4%), followed by falls (35.1%) and being struck by/against objects (11.6%). In school-aged children, injuries were most commonly sustained from falls (47.8%), followed by bicycle accidents (14%) and being struck by/against objects (12.5%). Compared to adults, there was no significant difference of the adjusted mortality of the preschool-aged children (AOR = 0.9; 95% CI 0.38⁻2.12; p = 0.792) but there were lower adjusted odds of mortality of the school-aged children (AOR = 0.4; 95% CI 0.10⁻0.85; p = 0.039). The school-aged children had lower odds of mortality than adults (OR, 0.2; 95% CI, 0.06⁻0.74; p = 0.012), but such lower odds of risk of mortality were not found in preschool-aged children (OR, 0.7; 95% CI, 0.29⁻1.81; p = 0.646). Conclusions : This study suggests that specific types of injuries from different injury mechanisms are predominant among preschool-aged and school-aged children. The school-aged children had lower odds of mortality than adults; nonetheless there was no difference in mortality rates of preschool-aged children than adults, with or without controlling for sex, injury mechanisms and ISS. These results highlight the importance of injury prevention, particularly for preschool-aged children in Southern Taiwan.

Asthma affects more than two million Australians, and of growing concern for the Australian health system is asthma in the over 65+ age group. Between 1997 and 2001, 61% of all deaths attributable to asthma occurred in people aged over 65 and mortality in this group remains higher than the rate for all other groups. An investigation of older Australians' perceptions of asthma prevalence and impact was conducted in the Illawarra region of New South Wales. Eight focus groups with the target audience were conducted to explore their attitudes, knowledge and skills with regard to asthma symptoms, prevalence, diagnosis and treatment. Additionally, 12 in-depth interviews were conducted with a broad range of health professionals to ascertain their opinion of the target audience's asthma knowledge and understanding. Results indicate that these older Australians are unaware of the prevalence and severity of asthma in their age group, have limited understanding of symptoms and treatments, and associate the condition with children. Health professionals reported that older people minimise respiratory symptoms as a natural part of ageing. Qualitative analysis using the Health Belief Model, suggests that heightened knowledge and awareness is necessary to bring about voluntary behaviour change in order to reduce asthma mortality and morbidity in the 65+ age group.

Aim To quantify the contribution of changes in different risk factors population levels and treatment uptake on the decline in CHD mortality in Denmark from 1991 to 2007 in different socioeconomic groups. Design We used IMPACTSEC, a previously validated policy model using data from different population registries. Participants All adults aged 25–84 years living in Denmark in 1991 and 2007. Main outcome measure Deaths prevented or postponed (DPP). Results There were approximately 11,000 fewer CHD deaths in Denmark in 2007 than would be expected if the 1991 mortality rates had persisted. Higher mortality rates were observed in the lowest socioeconomic quintile. The highest absolute reduction in CHD mortality was seen in this group but the highest relative reduction was in the most affluent socioeconomic quintile. Overall, the IMPACTSEC model explained nearly two thirds of the decline in. Improved treatments accounted for approximately 25% with the least relative mortality reduction in the most deprived quintile. Risk factor improvements accounted for approximately 40% of the mortality decrease with similar gains across all socio-economic groups. The 36% gap in explaining all DPPs may reflect inaccurate data or risk factors not quantified in the current model. Conclusions According to the IMPACTSEC model, the largest contribution to the CHD mortality decline in Denmark from 1991 to 2007 was from improvements in risk factors, with similar gains across all socio-economic groups. However, we found a clear socioeconomic trend for the treatment contribution favouring the most affluent groups. PMID:29672537

From January 1994 to July 2004, 323 patients underwent 348 revascularization of carotid bifurcation for atherosclerotic stenoses. Eighty eight patients (group A) were 75 year-old or older, whereas 235 (group B) were younger than 75 years. Postoperative mortality/neurologic morbidity rate was 1% in group A, and 1.4% in group B. At 5 years, patency and freedom from symptoms/stroke were, respectively, 91% and 92% in group A, and 89% and 91% in group B. None of these differences was statistically significant. In the same time period, 26 internal carotid arteries were revascularized in 24 patients, 75 or more aged, for a symptomatic kinking. Postoperative mortality/morbidity rate was absent, whereas, at 5 years, patency and freedom from symptoms/stroke were, respectively, 88% and 92%. Twelve vertebral arteries were revascularized in 12 patients, 75 or more aged, for invalidating symptoms of vertebrobasilar insufficiency. Postoperative mortality/neurologic morbidity rate was absent. In one case postoperative recurrence of symptoms occurred, despite a patent revascularization. Patency and freedom from symptoms/stroke were 84% and 75%, at 5 years. Revascularization of carotid and vertebral arteries in the elderly can be accomplished with good results, superposable to those of standard revascularization of carotid bifurcation in a younger patients' population.

Persons with certain neurological conditions have higher mortality rates than the population without neurological conditions, but the risk factors for increased mortality within diagnostic groups are less well understood. The interRAI CHESS scale has been shown to be a strong predictor of mortality in the overall population of persons receiving health care in community and institutional settings. This study examines the performance of CHESS as a predictor of mortality among persons with 11 different neurological conditions. Survival analyses were done with interRAI assessments linked to mortality data among persons in home care (n = 359,940), complex continuing care hospitals/units (n = 88,721), and nursing homes (n = 185,309) in seven Canadian provinces/territories. CHESS was a significant predictor of mortality in all 3 care settings for the 11 neurological diagnostic groups considered after adjusting for age and sex. The distribution of CHESS scores varied between diagnostic groups and within diagnostic groups in different care settings. CHESS is a valid predictor of mortality in neurological populations in community and institutional care. It may prove useful for several clinical, administrative, policy-development, evaluation and research purposes. Because it is routinely gathered as part of normal clinical practice in jurisdictions (like Canada) that have implemented interRAI assessment instruments, CHESS can be derived without additional need for data collection.

Trends in motor vehicle deaths in Wisconsin, 1986-1996: a decade of progress?

Motor vehicle-related injuries are a major cause of death and economic burden in Wisconsin. We examined motor vehicle-related mortality trends in Wisconsin from 1986 to 1996. During this time, overall mortality decreased by 12% and Wisconsin has met its year 2000 goal. However, mortality rates did not improve for women and non-whites. In addition, mortality rates increased in persons over 75 years. There are several explanations that may account for the overall mortality rate decline, but the reasons for the differences between age, racial, and gender groups are unclear.

Screening Mammography & Breast Cancer Mortality: Meta-Analysis of Quasi-Experimental Studies

2014-01-01

Background The magnitude of the benefit associated with screening has been debated. We present a meta-analysis of quasi-experimental studies on the effects of mammography screening. Methods We searched MEDLINE/PubMed and Embase for articles published through January 31, 2013. Studies were included if they reported: 1) a population-wide breast cancer screening program using mammography with 5+ years of data post-implementation; 2) a comparison group with equal access to therapies; and 3) breast cancer mortality. Studies excluded were: RCTs, case-control, or simulation studies. We defined quasi-experimental as studies that compared either geographical, historical or birth cohorts with a screening program to an equivalent cohort without a screening program. Meta-analyses were conducted in Stata using the metan command, random effects. Meta-analyses were conducted separately for ages screened: under 50, 50 to 69 and over 70 and weighted by population and person-years. Results Among 4,903 published papers that were retrieved, 19 studies matched eligibility criteria. Birth cohort studies reported a significant benefit for women screened

Asian Indians had one of the highest population growth rates in California between 1990 and 2000. However, few studies have examined common causes of death in this ethnic group in California. We examined leading causes of mortality in Asian Indians in California and analyzed differences across age and sex. Linear interpolation of 1990 and 2000 US Census data were used to calculate population sizes. California mortality data were examined to determine total number of Asian Indian deaths, and analyzed to determine causes of death across age (25-44, 45-64, > or = 65) and sex subgroups. International Classification of Diseases, 9th and 10th revision codes were used to aggregate causes of mortality into disease categories of cardiovascular diseases, cancers, diabetes, traumas/accidents/suicides, infections, and other conditions. Cardiovascular diseases were the leading cause of death for both sexes. Cancers were the second leading cause of death for both sexes. Diabetes and traumas/accidents/suicides were the next most common cause of mortality for females and males respectively. However, differences were found between age groupings across the sexes. This analysis confirms leading causes of death found in other densely-populated Asian Indian regions. It also sheds light on emerging conditions in this population in California. Although contributors to causes of mortality are discussed, more research is needed to understand the unique biological and socio-cultural determinants of disease in Asian Indians. Translation of this research into intervention strategies will reduce the burden of these diseases in this rapidly-growing population in California and the United States.

Every year official data is published which describes the care of patients with diabetes mellitus in the Czech Republic. An overall number of individuals with diabetes, the number of newly reported cases and the number of patient deaths is always specified. However this data does not allow us to identify the differences in mortality between the individual cohorts of diabetic patients in relation to therapy. Comparison of the mortality development in the periods of 2002-2006 and 2010-2013 in a representative sample of the patient population with type 2 diabetes mellitus using oral antidiabetic drugs, kept in the database of the General Health Insurance Company of the Czech Republic (VZP) which provided health care coverage for 63% of Czech population in 2013. A retrospective epidemiologic analysis. We identified all individuals in the VZP database who had a record of DM diagnosis (E10-E16 based on ICD 10) or who had any antidiabetic therapy prescribed (ATC group A10) in the periods of 2002-2008 and 2009-2013. We only selected those patients for the analysis who were treated with oral antidiabetic medicines (in the given year or the preceding years they had a record of treatment with at least one medicine from A10B group, while having no record of treatment with medicines from A10A group within both years). 237,665 individuals met the selected criteria in 2003 and 315,418 individuals in 2013. Mortality rates dropped for all age groups (from 2003-2013): for 50-59 year olds by 1.2%-0.7%; in 60-69 year olds by 2.6%-1.6%; for 70-79 year olds by 5.8%-3.5%. In 2013 mortality rates came close to the general population where for the same age groups they reached 0.6%, 1.5% and 3.4% respectively. When expressed in relative terms, the mortality among 50-59 year olds declined by 42% (Czechia by 25%), among 60-69 year olds by 39% (Czechia by 17%) and among 70-79 year olds by 40% (Czechia by 28%) from the year 2003. The decline in mortality among the patients with DM treated with oral antidiabetic medicines was greater in both absolute and relative terms in the period of 2003-2013 than among the general population in the Czech Republic. The analysis of mortality among the patients treated with oral antidiabetic medicines, registered in the VZP database, has shown a clearly favourable trend of mortality decline which is faster than among the general population. The fact that mortality among this cohort is getting closer to that among the general population of the corresponding age is a finding of critical importance. There is a justified expectation that mortality, with increasingly extensive utilization of the present therapeutic procedures, will continue to decrease.

The War on Poverty’s Experiment in Public Medicine: Community Health Centers and the Mortality of Older Americans†

Bailey, Martha J.; Goodman-Bacon, Andrew

2015-01-01

This paper uses the rollout of the first Community Health Centers (CHCs) to study the longer-term health effects of increasing access to primary care. Within ten years, CHCs are associated with a reduction in age-adjusted mortality rates of 2 percent among those 50 and older. The implied 7 to 13 percent decrease in one-year mortality risk among beneficiaries amounts to 20 to 40 percent of the 1966 poor/non-poor mortality gap for this age group. Large effects for those 65 and older suggest that increased access to primary care has longer-term benefits, even for populations with near universal health insurance.

We analyzed international patterns and socioeconomic and rural-urban disparities in all-cause mortality and mortality from homicide, suicide, unintentional injuries, and HIV/AIDS among US youth aged 15-24 years. A county-level socioeconomic deprivation index and rural-urban continuum measure were linked to the 1999-2007 US mortality data. Mortality rates were calculated for each socioeconomic and rural-urban group. Poisson regression was used to derive adjusted relative risks of youth mortality by deprivation level and rural-urban residence. The USA has the highest youth homicide rate and 6th highest overall youth mortality rate in the industrialized world. Substantial socioeconomic and rural-urban gradients in youth mortality were observed within the USA. Compared to their most affluent counterparts, youth in the most deprived group had 1.9 times higher all-cause mortality, 8.0 times higher homicide mortality, 1.5 times higher unintentional-injury mortality, and 8.8 times higher HIV/AIDS mortality. Youth in rural areas had significantly higher mortality rates than their urban counterparts regardless of deprivation levels, with suicide and unintentional-injury mortality risks being 1.8 and 2.3 times larger in rural than in urban areas. However, youth in the most urbanized areas had at least 5.6 times higher risks of homicide and HIV/AIDS mortality than their rural counterparts. Disparities in mortality differed by race and sex. Socioeconomic deprivation and rural-urban continuum were independently related to disparities in youth mortality among all sex and racial/ethnic groups, although the impact of deprivation was considerably greater. The USA ranks poorly in all-cause mortality, youth homicide, and unintentional-injury mortality rates when compared with other industrialized countries.

Bighorn sheep mortality related to pneumonia is a primary factor limiting population recovery across western North America, but management has been constrained by an incomplete understanding of the disease. We analysed patterns of pneumonia-caused mortality over 14 years in 16 interconnected bighorn sheep populations to gain insights into underlying disease processes. 2. We observed four age-structured classes of annual pneumonia mortality patterns: all-age, lamb-only, secondary all-age and adult-only. Although there was considerable variability within classes, overall they differed in persistence within and impact on populations. Years with pneumonia-induced mortality occurring simultaneously across age classes (i.e. all-age) appeared to be a consequence of pathogen invasion into a naïve population and resulted in immediate population declines. Subsequently, low recruitment due to frequent high mortality outbreaks in lambs, probably due to association with chronically infected ewes, posed a significant obstacle to population recovery. Secondary all-age events occurred in previously exposed populations when outbreaks in lambs were followed by lower rates of pneumonia-induced mortality in adults. Infrequent pneumonia events restricted to adults were usually of short duration with low mortality. 3. Acute pneumonia-induced mortality in adults was concentrated in fall and early winter around the breeding season when rams are more mobile and the sexes commingle. In contrast, mortality restricted to lambs peaked in summer when ewes and lambs were concentrated in nursery groups. 4. We detected weak synchrony in adult pneumonia between adjacent populations, but found no evidence for landscape-scale extrinsic variables as drivers of disease. 5. We demonstrate that there was a >60% probability of a disease event each year following pneumonia invasion into bighorn sheep populations. Healthy years also occurred periodically, and understanding the factors driving these apparent fade-out events may be the key to managing this disease. Our data and modelling indicate that pneumonia can have greater impacts on bighorn sheep populations than previously reported, and we present hypotheses about processes involved for testing in future investigations and management.

To investigate the value of coexisting pneumonia and British Thoracic Society CURB-65 score in predicting early mortality in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). In this prospective study, 483 consecutive in-patients with AECOPD were recruited between January 2010 and September 2012, including 295 males and 188 females. The patients were aged 45 to 92 years. They were divided into 2 groups: non-pneumonia (npAECOPD) and with pneumonia (pAECOPD). The start point of this study was the date when the patients were admitted into the respiratory ward, and the endpoint was the 30 day mortality. Clinical and demographic data were collected for all the patients, and the value of coexisting pneumonia and CURB-65 in predicting in-hospital mortality and 30 day mortality were assessed and compared. According to the inclusion/exclusion criteria, eventually 457 patients were included in this research, with 278 males and 179 females, and an average age of (75 ± 9) years. Of the 457 patients, 120 (26.3%) patients were in the pAECOPD group and 337 (73.7%) patients in the npAECOPD group. The in-hospital mortality, the 30 day mortality and the assisted ventilation rate were significantly higher in the pAECOPD group as compared to the npAECOPD group 18.3% (22/120) vs 4.7% (16/337), 21.7% (26/120) vs 7.4% (25/337); 49.2% (59/120) vs 27.0% (91/337), χ(2) = 18.1 - 21.4, all P < 0.05, respectively. Furthermore, the in-hospital mortality of the pAECOPD patients with CURB-65 score < 2, = 2 and > 2 was 4.4% (2/45), 15.2% (7/46) and 44.8% (13/29), respectively, while that of the npAECOPD patients was 0.9% (1/113), 3.4% (4/119) and 10.5% (11/105), respectively. The 30 day mortality of the pAECOPD patients with CURB-65 score < 2, = 2 and > 2 was 4.4% (2/45), 19.6% (9/46) and 51.7% (15/29), respectively, while that of the npAECOPD patients was 0.9% (1/113), 5.0% (6/119) and 17.1% (18/105), respectively. Stratified by CURB-65 Score, the in-hospital and 30 day mortality were both significantly higher in the pAECOPD group than in the npAECOPD group when CURB-65 was ≥ 2 (χ(2) = 5.8 - 10.1, P < 0.05 and P < 0.01, respectively). The AUROC analysis of CURB-65 as a predictor for early mortality resulted in an area under curve of 0.744. In patients with AECOPD, coexisting pneumonia is not only a risk factor for in-hospital mortality, but also a predictor for the treatment of assisted ventilation. CURB-65 score may be a good predictor for early mortality in patients with AECOPD.

Ischemic stroke accounts for 70% to 80% of all strokes, but intracerebral and subarachnoid hemorrhagic strokes have greater fatality. Age-standardized death rates from overall stroke are higher among men than women, but little is known about sex differences in stroke subtype mortality by race/ethnicity. We analyzed 1995 to 1998 national death certificate data to compare sex-specific age-standardized death rates (per 100 000) for ischemic stroke (n=507 256), intracerebral hemorrhagic stroke (n=98 709), and subarachnoid hemorrhagic stroke (n=27 334) among whites, blacks, American Indians/Alaska Natives, Asians/Pacific Islanders, and Hispanics. We calculated rate ratios and 95% CIs comparing women with men within age and racial/ethnic groups. Age-specific rates of ischemic and intracerebral hemorrhagic stroke deaths were lower for women than for men aged 25 to 44 and 45 to 64 years but were higher for ischemic stroke among older women, aged > or =65 years. Only among whites did women have higher age-standardized rates of ischemic stroke. Age-standardized death rates for intracerebral hemorrhagic stroke among women were lower than or similar to those among men in all racial/ethnic groups. Women had higher risk of death from subarachnoid hemorrhagic; this sex differential increased with age. The female-to-male mortality ratio differs for stroke subtypes by race/ethnicity and age. A primary public health effort should focus on increasing the awareness of stroke symptoms, particularly among people at high risk, to decrease delay in early detection and effective stroke treatment.

Active glycemic control has been proven to delay the onset and slow the progression of diabetic retinopathy, nephropathy, and neuropathy in diabetic patients, but the optimal level is obscure in end-stage renal disease. In this study, we evaluated the effect of hemoglobin A1c (HbA1c) on mortality of diabetic patients on dialysis, focusing on age and dialysis type. Of 3,302 patients enrolled in the prospective cohort for end-stage renal disease in Korea between August 2008 and October 2013, 1,239 diabetic patients who had been diagnosed with diabetes or having HbA1c≥6.5% at the time of enrollment were analyzed. Age was categorized as <55, 55-64 and ≥65 years old. Age, sex, modified Charlson comorbidity index, hemoglobin, primary renal disease, body mass index, and dialysis duration were adjusted. A total of 873 patients received hemodialysis (HD) and 366 underwent peritoneal dialysis (PD). During the mean follow-up of 19.1 months, 141 patients died. Patients with poor glucose control (HbA1c≥8%) showed worse survival than patients with HbA1c<8% (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.48-3.29; P<0.001). Subgroup analysis divided by age revealed that HbA1c≥8% was a predictor of mortality in age <55 (HR, 4.3; 95% CI, 1.78-10.41; P = 0.001) and age 55-64 groups (HR, 3.3; 95% CI, 1.56-7.05; P = 0.002), but not in age ≥65 group. Combining dialysis type and age, poor glucose control negatively affected survival only in age < 55 group among HD patients, but it was significant in age < 55 and age 55-64 groups in PD patients. Deaths from infection were more prevalent in the PD group, and poor glucose control tended to correlate with more deaths from infection in PD patients (P = 0.050). In this study, the effect of glycemic control differed according to age and dialysis type in diabetic patients. Thus, the target of glycemic control should be customized; further observational studies may strengthen the clinical relevance.

Tree mortality in mature riparian forest: Implications for Fremont cottonwood conservation in the American southwest

USGS Publications Warehouse

Andersen, Douglas

2015-01-01

Mature tree mortality rates are poorly documented in desert riparian woodlands. I monitored deaths and calculated annual survivorship probability (Ps) in 2 groups of large (27–114 cm DBH), old (≥40 years old) Fremont cottonwood (Populus fremontii Wats.) in a stand along the free-flowing Yampa River in semiarid northwestern Colorado. Ps = 0.993 year-1 in a group (n = 126) monitored over 2003–2013, whereas Ps = 0.985 year-1 in a group (n = 179) monitored over the same period plus 3 earlier years (2000–2003) that included drought and a defoliating insect outbreak. Assuming Ps was the same for both groups during the 10-year postdrought period, the data indicate that Ps = 0.958 year-1 during the drought. I found no difference in canopy dieback level between male and female survivors. Mortality was equal among size classes, suggesting Ps is independent of age, but published longevity data imply that either Ps eventually declines with age or, as suggested in this study, periods with high Ps are interrupted by episodes of increased mortality. Stochastic population models featuring episodes of low Ps suggest a potential for an abrupt decline in mature tree numbers where recruitment is low. The modeling results have implications for woodland conservation, especially for relictual stands along regulated desert rivers.

Objectives  To estimate the short term effect of particulate air pollution (particle diameter <10 μm, or PM 10 ) on mortality and explore the heterogeneity of particulate air pollution effects in major cities in China. Design  Generalised linear models with different lag structures using time series data. Setting  38 of the largest cities in 27 provinces of China (combined population >200 million). Participants  350 638 deaths (200 912 in males, 149 726 in females) recorded in 38 city districts by the Disease Surveillance Point System of the Chinese Center for Disease Control and Prevention from 1 January 2010 to 29 June 2013. Main outcome measure  Daily numbers of deaths from all causes, cardiorespiratory diseases, and non-cardiorespiratory diseases and among different demographic groups were used to estimate the associations between particulate air pollution and mortality. Results  A 10 µg/m 3 change in concurrent day PM 10 concentrations was associated with a 0.44% (95% confidence interval 0.30% to 0.58%) increase in daily number of deaths. Previous day and two day lagged PM 10 levels decreased in magnitude by one third and two thirds but remained statistically significantly associated with increased mortality. The estimate for the effect of PM 10 on deaths from cardiorespiratory diseases was 0.62% (0.43% to 0.81%) per 10 µg/m 3 compared with 0.26% (0.09% to 0.42%) for other cause mortality. Exposure to PM 10 had a greater impact on females than on males. Adults aged 60 and over were more vulnerable to particulate air pollution at high levels than those aged less than 60. The PM 10 effect varied across different cities and marginally decreased in cities with higher PM 10 concentrations. Conclusion  Particulate air pollution has a greater impact on deaths from cardiorespiratory diseases than it does on other cause mortality. People aged 60 or more have a higher risk of death from particulate air pollution than people aged less than 60. The estimates of the effect varied across cities and covered a wide range of domain.

Analyses of historical or modern populations indicate a strong relationship between mortality level and standard of living, measured, among other factors, by degree of urbanization. The aim of this study was to assess mortality rates in children of up to 5 years of age in two populations living under different conditions in central modern Poland at the end of the 19th century: the rural parish of Kowal, under Russian partition, and Toruń, an industrial and urbanized centre under Prussian partition. Data on births and deaths were taken from birth certificate registries and from the Prussian statistics yearbooks for 1876-1894. Death rates of children aged 0-5 years were calculated, and also for annual age ranges. The urban population had lower birth rates (37.19‰), natural increase rates (8.0‰), population dynamics rates (1.26‰), which provide information about the relation between two components of a natural increase, i.e. births and deaths, and an over-mortality of boys in relation to girls. In the rural population these values were all higher: 53.67‰, 18.11‰ and 1.59‰ respectively. No impact was found of social stratification on child mortality in the wide age group of 0-5 years. However, for subsequent one-year age groups significant relationships between mortality level and size and industrialization level of the population centres were noted. The living conditions of infants in Toruń, although being in a better position as an area annexed by Prussia, were markedly worse than those of rural Kowal Parish. In the urban centre infant mortality was slightly over 269 for 1000 live born, and in Kowal Parish it was 163 for 1000 live born. The high infant mortality was balanced in Toruń by the higher mortality levels of children aged 2-5 years compared with Kowal Parish. Natural selection in the city had the greatest impact on infants, who did not have the protective influence of breast-feeding because women had to return to work shortly after giving birth. The lower infant mortality of mothers in the countryside due to longer breast-feeding led to larger family sizes. In 1871-1890 in the villages the number of children per women was about 7.42, whereas in Toruń it ranged from 4.4 to 5.2. The probability of death among children who survived the first year of life was higher in the countryside than the town. In the rural parish, perhaps because of cultural factors such as breast-feeding or working practices making full-time baby-sitting possible, children who did not reach the age of 1 year were not subjected to such intensive natural selection. Overall, differences in child mortality in the two centres in 19th central Poland resulted from ecological and cultural conditions, rather than from social and economical reasons (living under different partitions).

The aim of this study was to evaluate the impact of PCV10 pneumococcal vaccine on mortality from pneumonia in children less than one year of age in Santa Catarina State, Brazil, comparing the four years prior and the four years subsequent to the vaccine's introduction in 2010. This ecological study used data from the Mortality Information System and vaccination coverage of children less than one year. Data were grouped by municipalities of residence and regions. Average mortality from pneumonia in children under one year decreased from 29.69 to 23.40 per 100,000, comparing 2006-2009 and 2010-2013, or a reduction of 11%. However there were differences between regions with a drop in mortality (Grande Florianópolis, Sul, Planalto Norte, and Nordeste) and others with an increase in the annual rates (Oeste, Itajaí, and Serra). In short, the state as a whole showed 11% reduction in mortality from pneumonia in children less than one year of age, four years after implementing routine PCV10 vaccination in the National Immunization Program, but with heterogeneous effects when comparing regions of the state.

Mammographic surveillance in women younger than 50 years who have a family history of breast cancer: tumour characteristics and projected effect on mortality in the prospective, single-arm, FH01 study.

2010-12-01

Evidence supports a reduction in mortality from breast cancer with mammographic screening in the general population of women aged 40-49 years, but the effect of family history is not clear. We aimed to establish whether screening affects the disease stage and projected mortality of women younger than 50 years who have a clinically significant family history of breast cancer. In the single-arm FH01 study, women at intermediate familial risk who were younger than 50 years were enrolled from 76 centres in the UK, and received yearly mammography. Women with BRCA mutations were not explicitly excluded, but would be rare in this group. To compare the FH01 cohort with women not receiving screening, two external comparison groups were used: the control group of the UK Age Trial (106,971 women aged 40-42 years at recruitment, from the general population [ie, average risk], followed up for 10 years), and a Dutch study of women with a family history of breast cancer (cancer cases aged 25-77 years, diagnosed 1980-2004). Study endpoints were size, node status, and histological grade of invasive tumours, and estimated mortality calculated from the Nottingham prognostic index (NPI) score, and adjusted for differences in underlying risk between the FH01 cohort and the control group of the UK Age Trial. This study is registered with the National Research Register, number N0484114809. 6710 women were enrolled between Jan 16, 2003, and Feb 28, 2007, and received yearly mammography for a mean of 4 years (SD 2) up until Nov 30, 2009; surveillance and reporting of cancers is still underway. 136 women were diagnosed with breast cancer: 105 (77%) at screening, 28 (21%) symptomatically in the interval between screening events, and three (2%) symptomatically after failing to attend their latest mammogram. Invasive tumours in the FH01 study were significantly smaller (p=0·0094), less likely to be node positive (p=0·0083), and of more favourable grade (p=0·0072) than were those in the control group of the UK Age Trial, and were significantly less likely to be node positive than were tumours in the Dutch study (p=0·012). Mean NPI score was significantly lower in the FH01 cohort than in the control group of the UK Age Trial (p=0·00079) or the Dutch study (p<0·0001). After adjustment for underlying risk, predicted 10-year mortality was significantly lower in the FH01 cohort (1·10%) than in the control group of the UK Age Trial (1·38%), with relative risk of 0·80 (95% CI 0·66-0·96; p=0·022). Yearly mammography in women with a medium familial risk of breast cancer is likely to be effective in prevention of deaths from breast cancer. Copyright © 2010 Elsevier Ltd. All rights reserved.

OBJECTIVES: To investigate the recent fall in mortality from breast cancer in England and Wales, and to determine the relative contributions of improvements in treatment and earlier detection of tumours. DESIGN: Retrospective study of all women with breast cancer registered by the East Anglian cancer registry and diagnosed between 1982 and 1989. SUBJECTS: 3965 patients diagnosed 1982-5 compared with 4665 patients diagnosed 1986-9, in three age groups 0-49, 50-64, > or = 65 years, with information on stage at diagnosis and survival. MAIN OUTCOME MEASURES: Three year relative survival rates by time period, age group, and stage; relative hazard ratios for each time period and age group derived from Cox's proportional hazards model, adjusted for single year of age and stage. RESULTS: Survival improved in the later time period, although there was little stage specific improvement. The proportion of early stage tumours increased especially in the 50-64 year age group, and adjustment for stage accounted for over half of the improvement in survival in women aged under 65 years. CONCLUSION: Over half of the drop in mortality in women aged under 65 years seems to be attributable to earlier detection of tumours, which has been observed since the mid-1980s. This could have resulted from an increase in breast awareness predating the start of the breast screening programme. PMID:9056796

Although hypothyroidism is associated with many comorbidities, the evidence for its association with all-cause mortality in older adults is limited. To evaluate the association between hypothyroidism and all-cause mortality in older adults. Population-based retrospective cohort study. National Health Insurance Research Database in Taiwan. After 1:10 age/sex/index year matching, 2029 patients aged ≥65 years who received a new diagnosis of hypothyroidism between 2001 and 2011, and 20290 patients without hypothyroidism or other thyroid diseases, were included in the hypothyroidism and non-hypothyroidism cohorts respectively. All-cause mortality was defined as the primary outcome. Cox proportional hazards regression models were used to calculate the hazard ratios (HRs) of mortality. To further evaluate the effect of thyroxine replacement therapy (TRT) on mortality, we divided patients with hypothyroidism into two groups: patients who received TRT and those who did not. Hypothyroidism was associated with an increased risk of all-cause mortality (adjusted HR [aHR] = 1.82, 95% confidence interval [CI] = 1.68-1.98, p < 0.001). Patients with hypothyroidism who received TRT had a lower risk of mortality than patients who did not receive TRT (aHR = 0.57, 95% CI = 0.49-0.66, p < 0.001). Similar results were obtained after further propensity score matching, in age-, sex-, and comorbidity-stratified analyses. Hypothyroidism was independently associated with increased all-cause mortality in older adults. In patients with hypothyroidism, TRT was associated with a lower risk of all-cause mortality.

Evidence of the association between global cognitive function and mortality is much, but whether specific cognitive function is related to mortality is unclear. To address the paucity of knowledge on younger populations in the US, we analyzed the association between specific cognitive function and mortality in young and middle-aged adults. We analyzed data from 5,144 men and women between 20 and 59 years of age in the Third National Health and Nutrition Examination Survey (1988–94) with mortality follow-up evaluation through 2006. Cognitive function tests, including assessments of executive function/processing speed (symbol digit substitution) and learning recall/short-term memory (serial digit learning), were performed. All-cause mortality was the outcome of interest. After adjusting for multiple variables, total mortality was significantly higher in males with poorer executive function/processing speed (hazard ratio (HR) 2.02; 95% confidence interval 1.36 to 2.99) and poorer recall/short-term memory (HR 1.47; 95% confidence interval 1.02 to 2.12). After adjusting for multiple variables, the mortality risk did not significantly increase among the females in these two cognitive tests groups. In this sample of the US population, poorer executive function/processing speed and poorer learning recall/short-term memory were significantly associated with increased mortality rates, especially in males. This study highlights the notion that poorer specific cognitive function predicts all-cause mortality in young and middle-aged males. PMID:27595105

A retrospective study was done of 73 consecutive Jehovah's Witness children less than 2 years of age who were operated on for lesions of the heart and major vessels. The series was divided into three groups: (1) neonates less than 31 days old, (2) children between 31 days and 2 years, and (3) children requiring cardiopulmonary bypass. The overall mortality rate for the series was 12.3% (9/73). Only three of the nine deaths were complicated by blood loss and anemia. The mortality rate for Group I was 18.2% (2/11). Only one of the two deaths was partly attributable to anemia. The overall mortality rate for Group II was 14.9% (7/47). Only two of these seven deaths were complicated by anemia. No deaths occurred among the 15 patients in Group III. Bloodless prime hemodilution techniques were used in all patients. Based upon our data, we have concluded that cardiac surgery can be performed when indicated on children of Jehovah's Witnesses with acceptable mortality rates and relatively straightforward perioperative care.

Evidence on cardiac resynchronization therapy (CRT) in older patients is scarce and conflicting. Nevertheless, CRT in the elderly is of major practical relevance as heart failure prevalence increases with age. The German Device Registry (DEVICE) is a nationwide, prospective registry with a longitudinal follow-up design investigating device implantations in 60 German centres. The present analysis of DEVICE focussed on perioperative complication rates and 1-year outcome of patients ≥75years (n=320) compared to younger patients (n=879) receiving a CRT device. Comorbidities were more common in older patients (chronic kidney disease (CKD): 27.5% vs. 21.5%, p=0.029; atrial fibrillation (AF): 26.9% vs. 15.6%, p<0.001). Despite higher NYHA classes in the older age group, ejection fractions were comparable (27.2±7.1% ≥75years, 26.2±7.1% <75years, p=0.06). Perioperative complications and mortality rates did not show significant difference between groups. After new device implantation, absolute 1-year mortality was higher in older patients (11.0% ≥75years, 6.4% <75years, p=0.014), with a significantly lower proportion of cardiac deaths in the older group (p=0.05). Patients ≥75years being alive after 1year had lower response rates, with chronic kidney disease (OR 0.46, p<0.05) and smaller QRS complexes (OR 0.31, p<0.01) being particular risk factors for missing improvement of heart failure symptoms. As expected severe heart failure (NYHA IV) was a strong independent predictor of death (HR 1.95, p=0.01), whereas AF as underlying rhythm could be worked out as predictor for mortality especially in the younger patients (HR 2.31, p=0.002). Patients ≥75years of age receiving a CRT device do not have a higher perioperative mortality and complication rate although comorbidities (CKD and AF) occur more frequently. The absolute 1-year mortality is higher; nevertheless, the proportion of cardiac deaths is even lower in the older patients reflecting a benefit of CRT in this group.

To estimate patients enrolling on antiretroviral therapy (ART) over time; describe trends in baseline characteristics; and compare immunological response, loss to follow-up (LTFU), and mortality by three age groups (25-39, 40-49 and ≥50 years). A retrospective observation cohort study. This study used routine ART data from two public clinics in Lilongwe, Malawi. All HIV-infected individuals, except pregnant or breastfeeding women, aged ≥ 25 years at ART initiation between 2006 and 2015 were included. Poisson regression models estimated risk of mortality, stratified by age groups. Of 37,378 ART patients, 3,406 were ≥ 50 years old. Patients aged ≥ 50 years initiated ART with more advanced WHO clinical stage and lower CD4 cell count than their younger counterparts. Older patients had a significantly slower immunological response to ART in the first 18 months on ART compared to patients aged 25-39 years (p = 0.04). Overall mortality rates were 2.3 (95% confidence Interval (CI) 2.2-2.4), 2.9 (95% CI 2.7-3.2) and 4.6 (95% CI 4.2-5.1) per 100 person-years in patients aged 25-39 years, 40-49 years and 50 years and older, respectively. Overall LTFU rates were 6.3 (95% CI 6.1-6.5), 4.5 (95% CI 4.2-4.7), and 5.6 (95% CI 5.1-6.1) per 100 person years among increasing age cohorts. The proportion of patients aged ≥ 50 years and newly enrolling into ART care remained stable at 9% while the proportion of active ART patients aged ≥50 years increased from 10% in 2006 to 15% in 2015. Older people had slower immunological response and higher mortality. Malawi appears to be undergoing a demographic shift in people living with HIV. Increased consideration of long-term ART-related problems, drug-drug interactions and age-related non-communicable diseases is warranted.

Long-term follow-up data on the effects of screening are scarce, and debate exists on the relative contribution of screening versus treatment to breast cancer mortality reduction. Our aim was therefore to assess the long-term effect of screening by age and time of implementation. We obtained data on 69,630 breast cancer deaths between 1980 and 2010 by municipality (N = 431) and age of death (40-79) in the Netherlands. Breast cancer mortality trends were analyzed by defining the municipality-specific calendar year of introduction of screening as Year 0. Additionally, log-linear Poisson regression was used to estimate the turning point in the trend after Year 0, per municipality, and the annual percentage change (APC) before and after this point. Twenty years after introduction of screening breast cancer mortality was reduced by 30% in women aged 55-74 and by 34% in women aged 75-79, compared to Year 0. A similar and significant decrease was present in municipalities that started early (1987-1992) and late (1995-1997) with screening, despite the difference in availability of effective adjuvant treatment. In the age groups 55-74 and 75-79, the turning point in the trend in breast cancer mortality was estimated in Years 2 and 6 after the introduction of screening, respectively, after which mortality decreased significantly by 1.9% and 2.6% annually. These findings show that the implementation of mammography screening in Dutch municipalities is associated with a significant decline in breast cancer mortality in women aged 55-79, irrespective of time of implementation. © 2017 UICC.

Aortic pulse wave velocity (PWV) is widely used as a noninvasive index of arterial stiffness and was used in the present study to investigate the relationship between PWV and cardiovascular mortality in the middle-aged and elderly Japanese population using a longitudinal study design. From 1988 to 2003, a total of 3,960 men (50-69 years old at baseline) who underwent medical check-ups and measurement of PWV, which was standardized for diastolic blood pressure, were recruited and divided into 4 groups according to the PWV values. The average follow-up period was 8.2 years. Mortality from all-causes and from cardiovascular disease significantly increased as PWV increased in the entire follow-up period. Multivariate-adjusted relative risks of all-cause and cardiovascular disease mortality for the highest quartile of PWV (>9.0 m/s) were 1.28 (95% confidence interval (CI) 0.97-1.68) and 1.83 (95%CI 1.02-3.29), respectively, compared with the lowest quartile (<7.5 m/s). An increased PWV can predict cardiovascular mortality in middle-aged and elderly Japanese men.
